visual c++源码一定对你有一定的帮助

#include   <stdio.h>

struct Struct1
{
    int     x;
    int     y;
};

struct Struct2 : Struct1
{
    int     z;
};

int main()
{
Struct2   s;

    printf ("sizeof (Struct1) is %d\n", sizeof (Struct1));
    printf ("sizeof (Struct2) is %d\n", sizeof (Struct2));
    s.x = 1;
    s.y = 2;
    s.z = 3;
    printf ("Structure member values are %d, %d and %d\n",
             s.x, s.y, s.z);
    return (0);
}
