Thread: Why does this work

Code:

#include <stdio.h>

int getInt()
{
    int b = 4;
    return b;
}

int main(int argc, char *argv[])
{
    int a;
    a = getInt();
    printf("this is a %d\n", a);
    return 0;
}

ive been under the idea that you cant do this because b is out of scope after getInt(). Once it returns from that method, b is lost. But this runs fine, prints out 4.

This is working because functions are meant for that only do some operations on some data, And return its value....

b value is returned from the function getInt thats why it is working fine.
