compile error: undeclared strcpy_s

I don't know how to solve this.

Answer 1

`strcpy_s` is a function declared in string.h header, since you're writing in C++ you can #include <cstring> to have this function available. The #include <string> in your code includes the C++ string header, which contains definitions and declarations for C++ string (std::string class)
