What is the difference between iostream , stdio.h and conio.h header files in c++?
<p>I am confused between all these three header files.I read it in Balagurusamy for C++ that all these files are used for taking input and output .But what is the difference.I know that we use stdio.h for scanf and printf and we use iostream for cin and cout.But what is the use of conio.h</p>
