Question

I don’t like to use <iostream> in C++ Library. I prefer to use something that is similar to “printf” and “scanf” in <stdio.h>.

Can I use Boost’s format library to replace <iostream> in all my C++ program ?

Answer 1

Boost Format only does the formatting bit. You still need iostream to actually make something appear on the screen.

Of course, using them together will achieve the parity with printf you are looking for. And it does so without sacrificing type-safety (though that’s not a huge issue these days, since the compiler will usually warn about bad printf arguments).
