A good way to create a flag variable

//Bad example
    int flag0 = 0;
    int flag1 = 1;
    int flag2 = 1;
    int flag3 = 0;
    int flag4 = 1;
    int flag5 = 0;
    int flag6 = 1;
    int flag7 = 0;

//Good example
    char flag;
    flag &= 127;
    flag |= 64;
    flag |= 32;
    flag &= 239;
    flag |= 8;
    flag &= 251;
    flag |= 2;
    flag &= 254;
