Recently, I do not know where VS has a problem. Every time I write the code, after compiling and running the code, the window is always flashing back. However, I do not want to reinstall, which is too troublesome. Here are some of the solutions I have put together. Please add more:
(Take the following code as an example)

#include<iostream>
using namespace std;
int main()
{
	cout << "hello world" << endl;
	return 0;
}

1. Press Ctrl+F5 to run the program
(This method only solves general flashbacks and may not be very useful)
2. Right-click on the project ->; Property – & gt; Configure properties ->; Connector – & gt; System – & gt; Subsystem – & gt; SUBSYSTEM right drop down window selection CONSOLE (/SUBSYSTEM:CONSOLE)

Int main(); int main(); system(“pause”);

4. C uses getchar() before return, C ++ uses cin. Get ();

Inline void keep_window_open(){char ch; cin> > ch; }, and then call the function at the end of main

6. Set breakpoint debugging, press F9 to set breakpoint, press F10 to step debugging, find the problem through debugging
