1. A string is nothing more than a character array.
2. All strings end with the NULL character.
3. Use the %s placeholder in the printf() function to display string values.

#include <stdio.h>
main ( )
{
    char *s1 = "abcd";
    char s2[] = "efgh";
    printf( "%s %16lu \n", s1, s1);
    printf( "%s %16lu \n", s2, s2);
    s1 = s2;
    printf( "%s %16lu \n", s1, s1);
    printf( "%s %16lu \n", s2, s2);
}
