Can we use printf,scanf functions in c++?if not why?

Answer 1

You can but it's not recommended if you plan on going for pure C++ style programming. As Luka has pointed out, some compilers (if not only VS) may throw errors.

Answer 2

You can use them but you need to include #include<cstdio> in your code.

Answer 3

Almost all C programs run in C++ too. So, you can use 'printf' and 'scanf'.

Answer 4

use cout and cin
