Answer 1

#include <iostream>

using namespace std;

int main()
{
	char key;

	do {
		cout << "Please choose a drink or \'T\' for the exit :" << endl << endl;
		cout << "\t[C] Coke" << endl;
		cout << "\t[S] San Miguel" << endl;
		cout << "\t[T] Quit" << endl;

		key = cin.get();
		cin.clear();
		while (cin.get() != '\n');
		key = tolower(key);
		if (key != 'c' && key != 's' && key != 't') {
			cout << "Incorrect input. Enter \'C\', \'S\' or \'T\'." << endl << endl;
		}

		switch (key)
		{
		case 'c': cout << "\tCoke 1.5l - 65.00" << endl; break;
		case 's': cout << "\t San Miguel 1l - 120.00" << endl; break;
		default:
			break;
		}
		cout << endl;
	} while (key != 't');

	return 0;
}
