Resolution change often

[KiranR]

while using the Turbo C++ application after execution of program... the screen resolution of the monitor just switches to 800x600. this happens often but not always. sometimes by its own the resolution changes

When Turbo C++ and it's graphics library was released 20 years ago, 800x600 was considered "Hi-Res". So the ancient application you're using simply does not know how to revert back to your native resolution.
