Function prototype in C is used by the compiler to ensure whether the function call matches the return type and the correct number of arguments or parameters with its data type of the called function. In the absence of the function prototype, a coder might call function improperly without the ...
Function Prototype In C++, the code of function declaration should be before the function call. However, if we want to define a function after the function call, we need to use the function prototype. For example, // function prototypevoidadd(int,int);intmain(){// calling the function bef...
Notice the parameterint num[2][2]in the function prototype and function definition: // function prototypevoiddisplayNumbers(intnum[2][2]); This signifies that the function takes a two-dimensional array as an argument. We can also pass arrays with more than 2 dimensions as a function argument...
Complete parameter declarations (int a) can be mixed with abstract declarators (int) in the same declaration. For example, the following declaration is legal: C intadd(inta,int); The prototype can include both the type of, and an identifier for, each expression that's passed as an argument...

Pay attention to that in your program example you do not have a function prototype scope. The structure struct foo is declared in the file scope. static struct foo { int x; } pos(void) { return (struct foo) {10}; } So it is visible from its point of declaration. As for the str...
For example, if you specify the static storage-class specifier in a prototype, you must also specify the static storage class in the function definition.Complete parameter declarations (int a) can be mixed with abstract declarators (int) in the same declaration. For example, the following ...
