Just personal tastes.
std::stringis little more convenient.Usually char array (C style) used, when its needed to read, write big text fast.
does anyone know how to read a string from input using scanf and put it in "std::string" variable?
Read in char* buffer, then std::string s = buff.
I want direct way , I want to use std::string to avoid the char
scanf() is C function, it does not know C++ class string. The only way to read C++ string is to say where to write data, but it is unsafe. So, there is no direct way.
