char *cStr = "C++"; std::string Str = std::string(cStr); - string to char* std::string str = "string"; const char *cstr = str.c_str(); 由于cstr是const的,不能被修改,如果想要修改的话,可以另拷贝一份再修改: std::string str = "string"; char *cstr = new char[str.length()...
std::string to char* C++ 将 std::string 转换为 char* 目前没有直接进行转换的方法。必须通过string对象的c_str()方法,获取C-style的字符串: std::stringstr="string";constchar*cstr =str.c_str(); 注意,该方法返回的类型为const char *,不能直接修改返回的C-style字符串,若需要修改则必须先拷贝该字...
In Visual C++ 2005 and in Visual C++ 2008, you must add the common language runtime support compiler option (/clr:oldSyntax) to successfully compile the previous code sample. To add the common language runtime support compiler option, follow these steps: ...
