C++ Variables

Variables

Variables are containers for storing data values.

In C++, there are different types of variables (defined with different keywords), for example:

  •     int - stores integers (whole numbers), without decimals, such as 123 or -123

  •     double - stores floating point numbers, with decimals, such as 19.99 or -19.99

  •     char - stores single characters, such as 'a' or 'B'. Char values are surrounded by single quotes

  •     string - stores text, such as "Hello World". String values are surrounded by double quotes

  •     bool - stores values with two states: true or false
