Changes for C++

If you want to write the same program in c++ apply the following changes to the program.

1.) change the header file from "#include<stdio.h>" to "#include<iostream>.h" 

2.)  for input & output use "cout<<" & "cin>>" instead of "printf" & "scanf".

3.) don't use "% "symbol and "&" sign in "cin>>" statement.
