Question

I know how to do it with cout:

cout << "string" << 'c' << 33;

But how to perform this so output is redirected to variable instead directly to standard out ?

const char* string << "string" << 'c' << 33; //doesn't work

Answer 1

Use std::stringstream from C++ standard library.

It works like the following:

std::stringstream ss;
ss << "string" << 'c' << 33;
std::string str = ss.str();
const char* str_ansi_c = str.c_str();

Keep in mind str still needs to be in the scope while you are using C-style str_ansi_c.
