This article mainly explains "how to solve the problem that VS2022 cannot be used". Friends who are interested may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to solve the problem that VS2022 can't be used.

Introduction

# include contains all the header files currently contained in C++, also known as universal header files, which are almost open-hanging.

The header files you need for programming are basically included in the universal header file, so imagine putting several line header files:

# include#include#include#include#include.

It's not simple and rude to use only one line of code # include instead!

How to use Universal head in VS2022

Unfortunately, such a good universal head can not be used in VS2022, should we just give up?

No, as a thoughtful youth of the 21st century, how can this problem be mine?

First, find your local VS installation directory, find the include folder in VS, and mine is on that path:

D:\ Microsoft Visual Studio\ 2022\ Community\ VC\ Tools\ MSVC\ 14.31.31103\ include

Create a bits folder under the include folder, and create a new stdc++.h file, copy the following code into the stdc++.h file, and you can use the universal header in VS2022.
