#include <iostream> using namespace std; int main() { int i = 1, n, odd = 0, even = 0; cin>>n; while(i <= n){ if (i%2!=0) odd += i; else even += i; i++; } cout<<"Even sum:"<<even<<"\n"; cout<<"Odd sum:"<<odd; return 0; }

it just adds 1 to the operand e.g. i += 1 is same as i++

I really dont know what while means even the sign ++,+=,+-, my prof focuses on smart students, he choose who to guide.

a += b is equivalent to a = a + b a -= b is equivalent to a = a - b a++ or ++a increments the value of 'a' by 1
