Answer 1

When you subtract the variables a and b from eachother in:
c=(a-b)/2;

Take the absolute value of a - b instead.
c = abs(a - b) / 2;

That way the order doesn't matter.

You can use abs from cmath, by writing #include <cmath> at the top of your program.

PS: I recommend using meaningful variable names.
