Learning the C++ syntax

Learning C++ syntax is crucial to write correct and reliable code, and the ability to write effective C++ code is a fundamental skill that C++ developers must possess. In this section, we will introduce the essentials of C++ syntax, beginning with data types.

Using the C++ data types

Besides the int data type that we just have used, C++ has many other built-in data types that can be used. Here is a list of some basic data types:

Data type	Size (bytes)	Description
int	4	Stores signed integer numbers without decimals. Data range: -2,147,483,648 to 2,147,483,647 Example: int i = -1; int j = 1;
unsigned int	4	Stores unsigned integer numbers without decimals. Data range: 0 to 4,294,967,295 ...
