Sometimes we will find that VS2010 will flash back, and we will not see the results after the program is executed. There are two solutions to this problem.

Solution a:
Add system(“pause”) before the program ends (before return);  
This is the pause instruction for the system and it’s going to pause and it’s not going to continue, so it’s not going to go back.

Scheme 2:
Steps to implement in VS: Project ->; Property – & gt; Configure properties ->; Connector – & gt; System – & gt; Select the console for the subsystem.
