Too few arguments ошибка

UPDATE :

Based on more recent comments, the problem is that the executable is named repeat, and you’re using csh or tcsh, so repeat is a built-in command.

Type ./repeat rather than repeat.

And when asking questions, don’t omit details like that; copy-and-paste your source code, any commands you typed, and any messages you received.

The executable is named file, which is also a command.

To run your own program, type

./file

EDIT :

The above was an educated guess, based on the assumption that:

• The actual compilation command was gcc file.c -o file or gcc -o file file.c; and
• The predefined file command (man file for information) would produce that error message if you invoke it without arguments.

The question originally said that the compilation command was gcc file.c; now it says gcc -o filename file.c. (And the file command prints a different error message if you run it without arguments).

The correct way to do this is:

gcc file.c -o filename && ./filename

(I’d usually call the executable file to match the name of the source file, but you can do it either way.)

The gcc command, if it succeeds, gives you an executable file in your current directory named filename. The && says to execute the second command only if the first one succeeds (no point in trying to run your program if it didn’t compile). ./filename explicitly says to run the filename executable that’s in the current directory (.); otherwise it will search your $PATH for it.

If you get an error message Too few arguments, it’s not coming from your program; you won’t see that message unless something prints it explicitly. The explanation must be that you’re running some other program. Perhaps there’s already a command on your system called filename.

So try doing this:

gcc file.c -o filename && ./filename

and see what happens; it should run your program. If that works, try typing just

filename

and see what that does. If that doesn’t run your program, then type

type -a filename

or

which filename

to see what you’re actually executing.

And just to avoid situations like this, cultivate the habit of using ./whatever to execute a program in the current directory.

C programming language

In this article, we are going to learn about an error which occurs in C programming language when we use less argument while calling a function. If we do this compiler will generate an error «Too few arguments to function».

Too few arguments to function in C language

This error occurs when numbers of actual and formal arguments are different in the program.

Let’s understand first, what actual and formal arguments are?

Actual arguments are the variables, values which are being passed while calling a function and formal arguments are the temporary variables which we declare while defining a function.

Consider the given example:

int sum(int a, int b, int c)
{
	return  (a+b+c);
}

int main()
{
	int x,y,z;
	x = 10; y = 20; z = 30;
	
	printf("sum = %dn",sum(x, y, z));
	
	return 0;
}

Here, actual arguments are x, y and z. Formal arguments are a, b and c.

When, the error «too few arguments to function is occurred»?

Remember: Number of actual arguments (the arguments which are going to be supplied while calling the function) must equal to number of formal arguments (the arguments which are declared while defining a function).

This error will occur if the number of actual and formal arguments is different.

Consider the above example, and match with these below given calling statements, these statements will generate errors:

printf("sum = %dn", sum(x, y));
printf("sum = %dn", sum(x));
printf("sum = %dn", sum(10, 20));

Example: (by calling functions with less number of arguments)

#include <stdio.h>

int sum(int a, int b, int c)
{
	return  (a+b+c);
}
int main()
{
	int x,y,z;
	x = 10; y = 20; z = 30;
	
	printf("sum = %dn", sum(x, y));
	printf("sum = %dn", sum(x));
	printf("sum = %dn", sum(10, 20));
	
	return 0;
}

Output

prog.c: In function ‘main’:
prog.c:12:23: error: too few arguments to function ‘sum’
  printf("sum = %dn", sum(x, y));
                       ^~~
prog.c:3:5: note: declared here
 int sum(int a, int b, int c)
     ^~~
prog.c:13:23: error: too few arguments to function ‘sum’
  printf("sum = %dn", sum(x));
                       ^~~
prog.c:3:5: note: declared here
 int sum(int a, int b, int c)
     ^~~
prog.c:14:23: error: too few arguments to function ‘sum’
  printf("sum = %dn", sum(10, 20));
                       ^~~
prog.c:3:5: note: declared here
 int sum(int a, int b, int c)
     ^~~
prog.c:9:10: warning: variable ‘z’ set but not used [-Wunused-but-set-variable]
  int x,y,z;
          ^

So, while calling a function, you must check the total number of arguments. So that you can save your time by this type of errors.

Example: (by calling functions with correct number of arguments)

#include <stdio.h>

int sum(int a, int b, int c)
{
	return  (a+b+c);
}
int main()
{
	int x,y,z;
	x = 10; y = 20; z = 30;
	
	printf("sum = %dn", sum(x, y, z));
	printf("sum = %dn", sum(x,y,z));
	printf("sum = %dn", sum(10, 20,30));
	
	return 0;
}

Output

sum = 60
sum = 60
sum = 60

Let’s start our topic with the basics of functions that we often use in Excel.

You must have a clear idea about what is a function in Excel. However, still, sometimes it is necessary for beginners to have a look at the fundamental features.

Basics of a Function

Basically, a block of code that lets you repeat any task is called a function. You can repeat it as much as you want. And it does not matter at all for what project you are trying to use it. For instance, you can create a function for the purpose of:

• Formatting an Excel sheet based on some conditions
• Using or showing user data
• Performing arithmetic calculations

 When you provide code reusing, you make codes free from idleness as well as bring down the maintenance slide. You don’t need to modify the same code for different sections. Well, you can enhance or even update the function as needed.

What parameters do you need to consider in a function?

It might be possible that the input data needed for action is passed into the function in terms of parameters or arguments. With functions, you can reverse back some values once an action is performed.

At times, you may have noticed an error “You’ve Entered Too Few Arguments For This Function” while working with Excel. It mainly happens when you don’t fill up the required spaces for the arguments to perform a function in an Excel formula.

Potential Causes

Why does this error occur? There can be a few possible reasons that lead to this error and we have all the possible solutions to it as well.

Example 1:

If you are likely to sum all the numbers given in the range A2:A10 with a condition that the numbers must be greater than 50, then you have to make sure to use the SUMIF function. You can write this formula as:

=SUMIF(A2:A10) 

What do you think? Will it be working? The answer is NO.

You need to mention three arguments for the SUMIF formula such as the criteria, the criteria range, and the sum range. Remember that the sum range is not mandatory when the sum range and criteria range is the same. That’s why the SUMIF function needs at least two arguments.

However, here you can see just 1 argument. That’s the reason you are experiencing an error “You’ve entered too few arguments for this function.”

Example 2:

By mistake, you cannot find this error. Let’s have a look at the below-given formula and see if it work or not.

=SUMIF(A2:A10 “>50”)

Actually, it also does not work. You will again find the same “You’ve Entered Too Few Arguments in this Function” error. Why it would not work?

Well, by default an Excel gives comma (,) for argument separator. It mainly happens when we say yes to the list separator in formulas. Or else you can use another list that is unaccepted in Excel. Keep in mind that Excel will not consider the above-written formulas as completely done. These formulas are not more than one argument. However, still, we have not provided the required arguments to the function that results in an error.  

So, what would be the right argument?

Here is the right formula:

=SUMIF(A2:A10,”>50”)

Example 3:

So, what do you think, the above formula will work or not? It hardly will cause any problem and restrict to working normally. Check if your system has a list separator such as colon, semicolon, or event space, so the formula will not work accordingly. You may have to experience an unwanted error.

You can change the list separator in your system. For this, you need to

Open the active window or press the Windows + R shortcut key. Now, type “intl. cpl” and press the enter key.

While doing this step, you should not add quotes. You will see a regional window. You will see in the bottom right corner of the window for additional settings.

Now is the right time to check the list separator and write “,” common or reset to default.

 Doing this will help Excel understand that the comma is a list separator. Ultimately, you will not experience the error “You’ve entered too few arguments in this function”.

Trying the same formula might not let you experience the same error. So, that’s it and this is how you remove the headache of getting an error “You’ve entered too few arguments in this function”.

Hopefully, this article has provided everything you need to clear out your concerns.

The syntax for arguments:

Function <Function name> ([argument1 [, argument2 [, argument3 [ …… ] ] ] ] ])

<function code>

End Function

For example:

With the function, you can print whether the customer is a senior citizen or not. The age of the function 

 ‘called function

Function typeofcustomer(age)

    If age &amp;amp;gt; 60 Then

        Debug.Print “Customer is a senior citizen”

    Else

        Debug.Print “Customer is not a senior citizen”

    End If

End Function

Sub findout()

    custage = InputBox(“Enter the age of the customer”)

‘calling function

    typeofcustomer (custage)

End Sub

Issue

I created a database that I have generated using a seeder, however now I wish for a user to input data and have me be allowed to see it on screen and add it to the database.

I also get this error when I input data and hit submit. It says:

ArgumentCountError Too few arguments to function
AppHttpControllersInventoryController::store(), 1 passed in
/var/www/html/vendor/laravel/framework/src/Illuminate/Routing/Controller.php
on line 54 and exactly 2 expected

http://localhost/inventories

This is my router, web.php:

<?php

use IlluminateSupportFacadesRoute;

Route::get('/', [AppHttpControllersHomeController::class, 'index'])->name('pages.index');

Route::get('/inventories', [AppHttpControllersInventoryController::class, 'index'])->name('index');

Route::get('/inventories/create',[AppHttpControllersInventoryController::class, 'create']);

Route::post('/inventories',[AppHttpControllersInventoryController::class,'store']);

This is my Controller, InventoryController.php:

<?php

namespace AppHttpControllers;

use AppModelsInventory;
use IlluminateHttpRequest;

/**
 * Class InventoryController
 */
class InventoryController extends Controller
{
    /**
     * Get the list of inventories.
     *
     * @return IlluminateContractsViewView
     */
    public function index()
    {
        $inventories = Inventory::all();
        return view('pages.inventories',[
            "inventories" => $inventories
        ]);
    }
    /**
     * @return IlluminateContractsViewView
     */
    public function create()
    {
        return view('pages.inventories.create');
    }
    /**
     * @param StorePostRequest $request
     *
     * @return IlluminateHttpRedirectResponse
     */
    public function store(Request $request, $inventory)
    {
        $validated = $request->validate();
        $request->validate([
            'title'=> 'required|string',
            'description'=> 'required|value:300',
            'price' => 'required|integer|min:0',
            'in_stock' => 'required|integer',
            'on_sale' => 'required|boolean'
        ]);
        $inventory = $request->query('title');
        $inventory = $request->query('description');
        $inventory = $request->query('price');
        $inventory = $request->query('in_stock');
        $name = $request->query('on_sale');

        return redirect()->route('/inventories');
    }
}

This is my Inventory.php model:

<?php

namespace AppModels;

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;

class Inventory extends Model
{
    use HasFactory;

    /**
     * @var array
     */
    protected $casts = [
        'on_sale' => 'boolean',
    ];
    /**
     * @var string[]
     */
    protected $fillable = [
        'title',
        'description',
        'price',
        'in_stock',
        'on_sale',
        'updated_at',
        'created_at'
    ];
    protected $guarded = [];
}

And this is my create.blade.php file where the user can input data(works fine but get error when I hit submit):

@extends('layouts.app')

@section('title', 'Create Inventory')

@section('content')
    <h1><strong>Please fill in the blanks to create an inventory.</strong></h1>
    <p><a href="/">Click here</a> to go back to the homepage.</p>
    <p><a href="/inventories">Click here</a> to go to the generated inventory page.</p>

    <form action="/inventories" method="post">
        @csrf
        <label for="title">Enter an item name:</label>
        <input type="text" name="title" required /><br><br>

        <label for="description">Enter the item's description:</label>
        <textarea name="description" required></textarea><br><br>

        <label for="price">Enter the item's price:</label>
        <input type="number" name="price" required/><br><br>

        <label for="in_stock">Enter a number of items in stock:</label>
        <input type="number" name="in_stock" required/><br><br>

        <label for="on_sale">Enter yes/no if item is on sale:</label>
        <input type="text" name="on_sale" required/><br><br>
        <button type="submit">Submit</button>
    </form>
@endsection

Any help would be useful as I am at a complete loss. I just wish to display the data that the user input on the inventories page and then add a message of whether it worked or didn’t work so the user knows. Thank you!

Solution

Your store method requires an $inventory to be passed to it :

public function store(Request $request, $inventory)

but your route doesn’t define a route parameter called $inventory :

Route::post('/inventories',[AppHttpControllersInventoryController::class,'store']);

so the error is telling you that there are too few arguments being passed (1 is passed) to the function (2 are expected). So first remove the extra parameter :

public function store(Request $request)

and then create a new inventory within the method before you start populating it with data :

$inventory = new Inventory();
$inventory = $request->query('title');
