Operators

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.

x = 3 + 2; // 5 // additionx = 3 - 2; // 1 // subtractionx = 3 * 2; // 6 // multiplicationx = 3 / 2; // 1 // divisionx = 3 % 2; // 1 // modulus (division remainder)

Notice that the division sign gives an incorrect result. This is because it operates on two integer values and will therefore truncate the result and return an integer. To get the correct ...
