This code works, but it run then close windows immediately. Need a fix :)

---

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

---

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

---

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

---

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;
  }

---

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

---

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