BYTE1 a;
BYTE2 b;
For variable a, only 7 bits are available and its range is (-127 to 127) = (+/-)2^7 -1.

If you use char as character, "unsigned" is completely ignored by the compiler just as comments are removed f...

What's the syntax for mod in java
...modular because n (mod m) IS ALWAYS >= 0 but not n % m. n % m is in the range > -m and < m. Although Java has a remainder operator for int and long types, it has no modulus function or operator. I.e., -12 % 10 = -2 whereas -12 mod 10 = 8. If % operator returns a negative value for n % m, th...
