Hi guys i wonder if u can help me im just tryin to create a simple menu using a switch function where the user can select a value from the list and go to that case. Ive got that working fine but i want it to validate that the number input by the user is within the values of the menu and that its not a char, so far ive got:
CODE
#include <iostream>
using namespace std;
const char BEEP = '\a';
void main ()
{
int selection;
system("cls");
cout << endl;
cout << "\t\t\t\t\Menu\n\n";
cout << "Welcome to menu...\n\n";
cout << "\t1 = Scenario 1\n";
cout << "\t2 = Scenario 2\n";
cout << "\t3 = Scenario 3\n";
cout << "\t0 = Scenario 0\n\n";
cout << "Please select an option from the menu: ";
cin >> selection;
while((!cin.good()) || (selection <0) || (selection >3))
{
cin.clear();
cout << BEEP <<"\nError! Please select a value from the menu (0-3): ";
cin.get();
cin >> selection;
}
switch (selection)
{
case 0:
system("cls");
cout << "\nScenario 0\n\n";
system("pause");
break;
case 1:
system("cls");
cout << "\nScenario 1\n\n";
system("pause");
break;
case 2:
system("cls");
cout << "\nScenario 2\n\n";
system("pause");
break;
case 3:
system("cls");
cout << "\nScenario 3\n\n";
system("pause");
break;
}
}
This works but if u enter more than one character then it loops around the error more than once, does anyone no how to prevent it doin this?
Cheers guys
