The General, who is a five star manager, is conducting a code review with his test developers.  “I’m looking at your code here boys.  I do very much admire your use of union utterings,” he says.

#include <stdio.h>

union yankee {
        int   bulletInt;
        float bulletFloat;
};

int main() {
        union yankee soldier;
        soldier.bulletInt = 111;
        printf("Int: %i\n", soldier.bulletInt);
        soldier.bulletFloat = 222.333333;
        printf("Float: %f\n", soldier.bulletFloat);
        /* clobbered by the float as expected */
        printf("Int: %i\n", soldier.bulletInt);
        return 0;
}

He continues, “However, I am a Yankee soldier with sympathetic tendencies towards the southern cause.  We’uns don’t put on our best suits when we go out and kill hogs; therefore, I do declare that we abolish the union in such a rightly manner as prescribed here.”

#include <stdio.h>

union yankee {
        int   bulletInt;
        float bulletFloat;
};

typedef union yankee confederate; 

int main() {
        confederate soldier;
        soldier.bulletInt = 111;
        printf("Int: %i\n", soldier.bulletInt);
        soldier.bulletFloat = 222.333333;
        printf("Float: %f\n", soldier.bulletFloat);
        /* clobbered by the float as expected */
        printf("Int: %i\n", soldier.bulletInt);
        return 0;
}
