The code will use the C++ Standard Library to input and output via streams, so it will use the <iostream> header. The code will use the C++ string type to handle input, so it will use the <string> header. Finally, it accesses the C runtime time and date functions, so the code will use the <ctime> header. These are all standard headers that will not change while you develop the project, so they are good candidates for precompiling.
In Visual Studio create a C++ header file and add the following lines:
#include <iostream> #include <string> #include <ctime>
Save the file as utils.h.
Now create a C++ source file and add a single line to include the header file you just created:
#include ″utils.h″
Save this ...
