Need Help Making a Menu

[LeMajestique]

I am having trouble making this menu, I followed some instructions online but I can't seem to get it to loop back to the menu after I am done with a menu selection. Please Help!

#include <iostream>
#include <string>

You need a break after each case otherwise it will continue through the cases.

So a case should look like:

case 1:
system ("CLS");
cout << "PYTHAGOREAN THEOREM CALCULATOR" << endl;
cout << "ENTER BOTH LEGS OF THE TRIANGLE" << endl;
int a, b;
float C;
cout << "LEG 1:";
cin >> a;
cout << "LEG 2:";
cin >> b;
C = sqrt ( ( a * a ) + ( b * b ) );
cout << "THE HYPONTENUSE IS:" << C << endl;
system ("PAUSE");
break;

Thanks so much!
