Several ways to do so, here are some possible one-line approaches:
Use getch() (need #include ).
Use getchar() (expected for Enter, need #include ).
Use cin.get() (expected for Enter, need #include ).
Use system("pause") (need #include ).
PS: This method will also print Press any key to continue . . . on the screen. (seems perfect choice for you :))
Edit: As discussed here, There is no completely portable solution for this. Question 19.1 of the comp.lang.c FAQ covers this in some depth, with solutions for Windows, Unix-like systems, and even MS-DOS and VMS.
