Hi. I've made a simple application that can calculate between meters and inches, centigrades and fahrenheit and a bunch of other things. My problem is that I've made it so the int main() thing has a menu (displayed using cout, then a cin to accept user input). When the user chooses an option, the program then uses a switch depending on which option was chosen. When the user has typed in some stuff to be calculated, the application is terminated. Is there a way to restart the application instead ?
