I was thinking this morning here, what would be the fastest way to reverse a number of positive to negative and from negative to positive, of course, the simplest way might be:
int a = 10; a = a*(-1);
or
int a = 10; a = -a;
But then, I thought, I take that to do this, using commands shift and pointers ... That really would be possible to change the sign of a value, using commands shift operators and memory?
Use something that is readable, such as
a *= -1;
a = -a;
Leave the rest to the optimizer.
