how to increase font size of output in turbo c++

Answer 1

By font size you mean the size of editor window or the words you cout on the output screen.
If its the editor window problem you can press ctrl+alt+Enter for full screen mode and again pressing the same will take you to windowed mode.
As for the characters displayed on the output screen , i haven't encountered any function aur method to increase its font size. Although if there is something like that then i would really like to know about it.

Answer 2
