1. Basic Types

In C + +, the declaration of a variable does not have to be placed in the front of the program like C and Fortran, and can be declared before the variable is used, increasing the readability of the program.

There are Boolean type variables in C + +, and the keyword is bool.

The numeric_limits template function in standard library in C + + can return the maximum and minimum values for different types of variables.

C + + identifiers require characters, numbers, and underscores, and identifiers must begin with a character or underscore, and the case of characters is differentiated.
