What is protyping in c?

Answer 1

prototyping is declaring the function , its returntype, type of argument passed so that the compiler just know what the function if not defined yet will be doing.

eg:-

int xyz(int,float); //this is the prototype

main()

{

int x;

x=xyz(4,3.55);

printf("%d",x);

}

int xyz(int a, float b) // actual definition of function

{

int c;

c=a + b;

return c;

}
