The function prototyping tells the number of arguments,type of arguments and type of the return type to the compiler.The function prototyping is a declaration statement in the calling program.

General Format:

returnType methodName(Argument List);

*Where Argument List specify the type and name of the arguments.

Example:

float Sum(float x,int y);

Or

float Sum(float,int);

Program:

int MAX(int,int); //Function Prototyping

void main()

{
int A,B;

cout<<”Enter the value for A and B”<<endl;

cin>>A>>B;

int R=MAX(A,B);

cout<<”MAX Is:”<<R<<endl;

}

int MAX(int x,int y) //Call by Value

{
if(x>y) return x;

return y;

}
