Can we use Cout instead of printf?

printf is formatted print while streams (cout) are “not”. Well, yes but not so much as printf. printf is big and slow function and for printing unformatted text puts or cout are preferred. C++14 and newer have printf implemented as a template function what reduces code quite a lot (eg if floats are not needed).
