hi,
Basic idea of return is:
suppose two functions want to communicate..then there should be one
communicating medium...that medium is called return value.means it return
value from a function and give that return value to other function to
communicate.that's why every function has a return value.
example
additiion of two number:
#include<stdio.h>
int sum_num(int a,int b)
main()
{
int a,b,sum;
printf("enter two numbers");
scanf("%d%d",&a,&b);
sum=sum_num(a,b);
printf("sum of two number=%d",sum);
return 0; //main is also a function.that's why it has return value
}
int sum_num(int a,int b)
{
int c;
c=a+b;
return c; //or return(a+b);
}
in the above example...main function comunication with add_sum function with
return value.
return value may be pointer...u can search example...
