C++ Arithmetic Operators
Perhaps you have warm memories of doing arithmetic drills in grade school. You can give that same pleasure to your computer. C++ uses operators to do arithmetic. It provides operators for five basic arithmetic calculations: addition, subtraction, multiplication, division, and taking the modulus. Each of these operators uses two values (called operands) to calculate a final answer. Together, the operator and its operands constitute an expression. For example, consider the following statement:
int wheels = 4 + 2;
The values 4 and 2 are operands, the + symbol is the addition operator, and 4 + 2 is an expression whose value is 6.
Here are C++'s five basic arithmetic operators:
The + operator adds its operands. For example, ...
