Convert a string of the string type to one belonging to the cstring type.

main.cpp

#include <cstdio>#include <iostream>#include "exchange.h"std::string str;char cstr[100];int main() { std::cin >> str; change2(str, cstr); puts(cstr); scanf("%s", cstr); std::cout << change1(cstr) << std::endl; return 0;}

exchange.h*

#include <cstring>std::string change1(const char* cstr){ std::string str_; str_ = cstr; return str_;}void change2(std::string str, char* cstr){ strcpy(cstr,str.c_str());}
