C++ uint8_t header

Introduction

uint8_t is a data type in C++ programming language. It is defined in the stdint.h header file, which provides typedefs for exact-width integer types.

What is uint8_t?

uint8_t is an unsigned 8-bit integer type. It represents values between 0 and 255 inclusively. This data type provides exact-width guarantees, which means that it is guaranteed to be 8 bits wide on any platform.

Usage

To use uint8_t, you have to include the stdint.h header file. This header file is part of the C++ Standard Library and should be available on any compliant C++ compiler.

#include <stdint.h>

uint8_t myByte = 255;

In the example above, we declare a variable called myByte and initialize it with the value 255. Since myByte is of type uint8_t, it can store values between 0 and 255 inclusively.

Benefits of using uint8_t

By using uint8_t instead of unsigned char, you ensure that the integer type has a guaranteed size of 8 bits. This is especially important when working with systems that have specific requirements for data types.

Additionally, uint8_t has a clearly defined range of values, which can help to prevent overflow and underflow errors.

Conclusion

In this article, we introduced uint8_t - an unsigned 8-bit integer type in C++. We discussed how to use it and its benefits over other integer types.
