Really lightweight (just header) implementation of std::string in plain WinAPI. (may be missing some features)
It's... simple?
#include <Windows.h>
#include "CString.hpp"
int main() {
CString str("katch is the best");
str.replace("katch", "xWhitey");
WriteConsoleA(GetStdHandle(STD_OUTPUT_HANDLE), str.c_str(), str.length(), NULL, NULL);
}
