Thread: Help with functions and cin

Hey all i am having 2 problems.
- first problem is that i am unable to run the code with the function inside the switch. For some reason it keeps giving me these errors:

f:\c++2\addressClass\addressClass.cpp(135): error C2050: switch expression not integral

- Second program i had (BEFORE placing everything into a function) is being able to input a large int for the phone number (5555555555) without it exiting the code and going back to the main.

Here is my code:

Code:

tryitout()
{
extPersonType thePerson;
addressType thePersonAddress;
dateType thePersonDate;
string fName, lName, theRelation, theAddress;
string theCity, theState;
int theZip, pNumber, theUserInput, repeat = 0, theDOBM;
int theDOBD, theDOBY;
	
	system("cls");
	cin.ignore();

	cout << "First Name: ";
	cin >> fName;

	cout << "Last Name: ";
	cin >> lName;

	cout << "Phone Number: ";
	cin >> pNumber;

	cout << "Relation (Family, Friend or Associate): ";
	cin >> theRelation;

	cout << "Address: ";
	getline(std::cin, theAddress);

	cout << "City: ";
	cin >> theCity;

	cout << "State: ";
	cin >> theState;

	cout << "Zip: ";
	cin >> theZip;

	cout << "DOB (Month): ";
	cin >> theDOBM;

	cout << "DOB (Day): ";
	cin >> theDOBD;

	cout << "DOB (Year): ";
	cin >> theDOBY;
				
	thePerson.setNameNum(fName, lName, pNumber, theRelation);
	thePersonAddress.setAddress(theAddress, theCity, theState, theZip);
	thePersonDate.setDate(theDOBM, theDOBD, theDOBY);

	thePersonAddress.printAddress();

	system("cls");
	cout << fName << " has been saved!" << endl;
	system("PAUSE");
	main();
}

int main(){

	system("cls");
	cout << "(1) Add a User" << endl;
	cout << "(2) View a User" << endl;
	cout << "(3) Search by Last Name" << endl;
	cout << "(0) Exit" << endl;
	cout << endl;
	cout << "Pick a number from above: ";
	
	do{
		cin >> theUserInput;
		repeat = 0;

		switch (theUserInput)
		{
			case 1:
				tryitout();				
			case 2:
				break;
			case 3:
				break;
			case 0:
				break;
			default:
				cout << "Thats not a number listed above..." << endl;
				repeat = 0;
				system("PAUSE");
		}
	} while(repeat != 0);

	system("PAUSE");
}

Any help would be great!
