此篇文章将要介绍c++字符串互相转换的说明,具体操作请看面的内容
  1.string vs char*
  //string to char*
  string str;
  const char* cch = str.c_str();
  char *ch = new char[strlen(cch)+1];
  strcpy(ch,cch);
  //char* to string
  string str = ch;
  2.string vs CString
  //CString to string
  CString cstr;
  string str = CStringA(cstr);
  //string to CString
  CString cstr = CString(str.c_str());
  3.CString vs char*
  //CString to char*
  CString cstr;
  int len = WideCharToMultiByte(CP_ACP, 0, cstr, -1, NULL, 0, NULL, NULL);
  char *ch = new char[len + 1];
  WideCharToMultiByte(CP_ACP, 0, cstr, -1, ch, len, NULL, NULL);
  //char* to CString
  CString cstr = CString(ch);
  4.int vs string
  //采用c++11新增函数stoi,stof,stol,to_string等进行数值与string之间的转换
  //string to int
  string str = “111”;
  int i = stoi(str);     
  //int to string
  string str = to_string(i);
  本文只提供了很多种转换方法中的一种,亲测有效!
