Answer 1

You can go to Start->Run, type cmd, cd to the project binary directory, then enter your executable name.

add this getch() or getchar() before return and the consolw window will stay till you enter something

Answer 3

You could declare a breakpoint at return 0; and run in debug.

Answer 4

Enable the 'Run in Terminal' Qt Creator project setting.

Answer 5

I don't know how QT Creators works but you could try.

Add:

char x;
cin>>x;

You'll have to type a letter and press enter to exit.

Or

#include<widows.h>
....
....
system("pause");
return 0;
}

OR

 #include<stdlib.h>
  ....
  ....
  cin.get();
  return 0;
  }

Answer 6

If you are just interested in viewing the output, it is shown in application output section of Qt Creator
