The function prototype (declaration) determines the number and type of arguments a function will accept. If the number or type of arguments passed to a function do not agree with its prototype, the compiler will notify you of the error.
That is, if the function only accepts one parameter, you cannot call the function by passing two or more arguments, since no such prototype exists. The compiler makes a best guess on which function you were trying to call (by the name you provided) and notifies you that the number or type of arguments do not agree with the available prototypes.
If the function is your own function, you can include the additional parameters as default values and re-implement the function to make use of those parameters, or you can overload the function to provide a completely new implementation that accepts the additional parameters. The new implementation may call the original implementation and embellish that implementation with its own implementation, or it can provide a completely separate implementation.
Note that no two functions can have the same name and signature within the same namespace. Every prototype must be unique and cannot differ by return type alone. That is, the number and/or type of arguments must differ in some way, with no ambiguity, so the compiler knows which function you are actually calling (as determined by the prototype).
In QBasic, a count mismatch error occurs when the number of arguments provided to a subroutine or function does not match the number expected by that subroutine or function. This can happen if too few or too many arguments are supplied, or if the data types of the arguments do not align with what is required. To resolve the issue, ensure that the correct number and type of arguments are being passed when calling the subroutine or function. Debugging and checking the subroutine definition can help identify where the mismatch occurs.

There are five types of functions and they are:Functions with no arguments and no return values.Functions with arguments and no return values.Functions with arguments and return values.Functions that return multiple values.Functions with no arguments and return values.Functions with no arguments and no return value.A C function without any arguments means you cannot pass data (values like int, char etc) to the called function. Similarly, function with no return type does not pass back data to the calling function. It is one of the simplest types of function in C. This type of function which does not return any value cannot be used in an expression it can be used only as independent statement.Functions with arguments and no return value.A C function with arguments can perform much better than previous function type. This type of function can accept data from calling function. In other words, you send data to the called function from calling function but you cannot send result data back to the calling function. Rather, it displays the result on the terminal. But we can control the output of function by providing various values as arguments. Functions with arguments and return value.This type of function can send arguments (data) from the calling function to the called function and wait for the result to be returned back from the called function back to the calling function. And this type of function is mostly used in programming world because it can do two way communications; it can accept data as arguments as well as can send back data as return value. The data returned by the function can be used later in our program for further calculations. Functions with no arguments but returns value.We may need a function which does not take any argument but only returns values to the calling function then this type of function is useful. The best example of this type of function is "getchar()" library function which is declared in the header file "stdio.h". We can declare a similar library function of own. Functions that return multiple values.So far, we have learned and seen that in a function, return statement was able to return only single value. That is because; a return statement can return only one value. But if we want to send back more than one value then how we could do this? We have used arguments to send values to the called function, in the same way we can also use arguments to send back information to the calling function. The arguments that are used to send back data are called Output Parameters.It is a bit difficult for novice because this type of function uses pointer
The asmlinkage tag tells gcc that that the function should not expect to find any of its arguments in registers (a common optimization), but only on the CPU's stack. Many kernel functions use the fact, that system_call consumes its first argument, the system call number, and leaves other arguments (which were passed to it in registers) on the stack. All system calls are marked with the asmlinkage tag, so they all look to the stack for arguments.
The AVERAGE function has up to 255 arguments in Excel.

Parameter passing is where we call a function with arguments. A parameter is simply another name for an argument.Examples:void f (void); // no arguments expectedvoid g (int); // one argument expectedvoid h (int, int=2); // two arguments expected (second argument is optional, defaulting to 2)f (); // okf (1); // error -- no argument expectedg (); // error -- one argument expectedg (2); // okg (0, 1); // error -- too many argumentsh (); // error -- at least one argument expectedh (4); // ok -- invokes h (4, 2)h (4, 5); // okh (4, 5, 6); // error -- too many argumentsArguments specified by a function are known as formal arguments. Arguments passed to the function are known as actual arguments. The actual arguments are always passed to the function by value unless the formal argument is a reference in which case the address of the actual argument is passed. If the formal argument is a pointer, it is passed by value. However, given that pointer values are memory address, this is the same as pass by reference. The only difference is that pointers may be null whereas references can never be null. If "no object" is a valid argument, the function should specify a pointer argument, otherwise it must specify a reference argument. Not all languages support references (C++ does, but C does not).
three parts
Arguments are enclosed in brackets. One set of brackets applies for a function, no matter how many arguments there are. So in a list a particular argument could have other arguments around it, all separated by commas. Here is the SUM function with one argument: =SUM(A2:A20) The IF function has 3 arguments: =IF(A3>50, D2*10, D2*20)
zero or more it can be fixed or variable (printf is an example)
What you put inside the brackets of a function are known as arguments. Some functions need a specific amount of arguments to work. If you put too many or too few, the function will not work. Other functions have optional arguments or are less specific about how many they need, so they do not give those kinds of errors. The version or type of file may also affect the functions, as some versions do not have the same functions and so they may not work or may work differently.

Too many arguments now = Too many arguments later
A function will have a name, brackets and inside the brackets certain values will be needed, depending on the function. Some functions, like NOW(), do not need anything inside the brackets. Most functions have a set number of values needed in the function, and many have ones that are optional.
