Return integer from the function in C by R4R Team

For return the integer value from the function we need to make the return type as a int.

Syntax-

int function_name()
{
return value;
}

Example-
int f()
{
return 1;
}
// no error

void f()
{
return 1;
}
// Give an error


program-

#include< stdio.h>
int function() //definition
{
printf("You make the function\n");
return 1;
}
int main()
{
int a;
printf("Inside main function\n");
a=function(); //calling
printf("%d",a);
return 0;
}

output-

Inside main function
You make the function
1

-In this program, we make a function named as function() have integer return type, this means that it only return the integer value.
-So function() return the value 1 by return 1; and this value is catch by the variable 'a' in main() function.
