Here are some of the Arithmetic operators in C++ listed from higher precedence to lower. We will learn more about them as the course progresses.
++ -- right * / % left + - left << >> left < <= > >= left == != left = += -= *= /= %= right , left int x = 5; x++; // Side effect is to increment x by 1. int a = 5, b = 3; int c, d; c = a % b; // % is the 'mod' or remainder operator; // c's value is set to 2 d = a/b; // d's value is 1, the integer quotient a += 10; // This is equivalent to a = a + 10;
