Operators

A numerical operator is a symbol that makes the program perform a specific mathematical or logical manipulation. The numerical operators in C++ can be grouped into five types: arithmetic, assignment, comparison, logical and bitwise operators.

Arithmetic Operators

There are the four basic arithmetic operators, as well as the modulus operator (%) which is used to obtain the division remainder.

int x = 3 + 2; // 5 // addition    x = 3 - 2; // 1 // subtraction    x = 3 * 2; // 6 // multiplication    x = 3 / 2; // 1 // division    x = 3 % 2; // 1 // modulus (division remainder)

Notice that the division sign gives an incorrect result. ...
