if we use 'num++' instead of 'num = num+1' what hppened

Answer 1

it the same thing num++ jst saves your time

Answer 2

'++num' is faster :-)
The ++ operators were once introduced to have a increment operator that maps to a single machine instruction. This might not be the case anymore but there's still a difference in non-optimized code. postfix ++ ('num++') and 'num=num+1' require a temporary to be constructed. '++num' doesn't. That's why it's faster.
