In this tutorial is explained how to use C++ variables and datatypes for beginners to programming.
It is perhaps not the most interesting part of learning C++ but it is basic stuff, very essential.
The basic data types in C++ are:
- bool : true or false (1 bit)
- char : Character 1 bit
- int16_t : 16 bit integer
- int32_t : 32 bit integer
- int64_t : 64 bit integer
- float : Floating-point
- double : Double precision floating point
- string : Text (from the STL library)
I recommend to follow along the simple example of the tutorial with Visual Studio 2019 to understand how to get started with these types in a simple console application.
