Here you are, then:

    /* sizeof(diff1) == sizeof(diff2) + sizeof('\0') */

    char diff1[] = "hello, world";
    char diff2[] = { 'h', 'e', 'l', 'l', 'o', ',',
                     ' ', 'w', 'o', 'r', 'l', 'd' };

    /* sizeof(same1) == sizeof(same2) == sizeof(diff2) */

    char same1[12] = "hello, world";
    char same2[12] = { 'h', 'e', 'l', 'l', 'o', ',',
                       ' ', 'w', 'o', 'r', 'l', 'd' };
