11. OPERATORS C++ An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. C++ is rich in built-in operators and provide the following types of operators: Arithmetic Operators Relational Operators Logical Operators Bitwise Operators Assignment Operators Misc Operators This chapter will examine the arithmetic, relational, logical, bitwise, assignment and other operators one by one. Arithmetic Operators There are following arithmetic operators supported by C++ language: Assume variable A holds 10 and variable B holds 20, then: Operator Description Example + Adds two operands A + B will give 30 - Subtracts second operand from the first A - B will give -10 * Multiplies both operands A * B will give 200 / Divides numerator by denumerator B / A will give 2 % Modulus Operator and remainder of after an integer division B % A will give 0 35
