You don't want conio.h. If you are using latest version of codeblocks, it probably means that you have MinGW as your compiler... MinGW does not contain <conio.h> as one of its header files, due to being a non-standard header.

For scanf, try #include <cstdio> , this should provide you with all the C-Style input and output functions.

We presume you have a really good reason for messing with scanf() in C++.

You are much better off just using the proper extraction operators.

Yes i have really very big reason ,in long test case, as scanf will consume lesser time wrt to cin

A common fallacy. Particularly in modern compilers.
