Solution for Exercise 18-11

#include <stdio.h>

int main()
{
    char a,b,c;
    char *p;

    a = 'A'; b = 'B'; c = 'C';

    printf("Know your ");
    p = &a;                 /* initialize */
    putchar(*p);            /*  use */
    p = &b;                 /* initialize */
    putchar(*p);            /*  use */
    p = &c;                 /* initialize */
    putchar(*p);            /*  use */
    printf("s\n");

    return(0);
}

Output

Know your ABCs

Notes

* Line 8 isn't a trick. I'm just taking advantage of the fact that the compiler ignores white space. So rather than separate each statement with an Enter key press, I used a space.
