(A useful web site for C++ language reference is: http://www.cppreference.com)
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;
