Your question makes no sense.
when we write definition of a function i.e; body of a function above main() function, then the function prototype be omitted. -Ramashankar Nayak,M.C.A,Pondicherry University
Syntax errors and prototype errors.
A prototype in C is the declaration of a function. Without a prototype, the function cannot be called because the compiler would have no way of knowing if the function was being called correctly. Prototypes may appear in multiple translation units but can only be defined once. A definition is itself a prototype.
If you want to use prototype it has to be declared before main(). If you have a function of type double with one argument of type int (with name arg), and the function name is func, then we have:#include ...double func(int arg);...int main(...){...return 0;}...double func(int arg){...}
yes

example: size_t strlen (const char *s);
One or more functions don't have a prototype. These functions should be either: - made static - have a prototype somewhere in a header (which is included into the same file)

You can write a program without specifying its prototype when the function returns an integer.If the prototype is not mentioned the compiler thinks that the return type of the function used is integer.When making program which return integer you can ignore writing the protoype.
// declare a function int* function(int, int); or int* (function)(int, int); // declare a pointer to a function int* (*pointer_to_function)(int, int);
*function();this declares a pointer function!
yes, we can not declare a function in the body of another function. but if we declare a function in the body of another function then we can call that very function only in that particular function in which it is declared; and that declared function is not known to other functions present in your programme. So if a function is required in almost all functions of your programme so you must declare it outside the main function i.e in the beginning of your programme.
