I have installed Dev-cpp on my computer and practising C++ programs. But what is annoying me is that I have to use a <conio.h> header with the .h extension. Moreover, a getch() function is to written at the end of every program.Otherwise no dispaly is shown. Why is ths happening? Why i have to use the conio with the .h extension everytime?  MinGw is the compiler(default) on my computer. Plz help me out.
