#include <stdio.h>
int main()

    int i1, i2;	/* two random integers */

    i1 = 4;
    i2 = 2;

    /* Nice way of writing the conditional */
    if ((i1 != 0) && (i2 != 0))

    /* Shorthand way of doing the same thing */
    /* Correct C code, but rotten style */
    if (i1 && i2)

    /* Incorrect use of bitwise and resulting in an error */
