Converting area unit

[davidc626]

I need to convert unit between Square metres Square feet.Here is my a part of code.

void Q1(){
	int opt;double UnitA;double UnitB;

	cout << "~Area conversion menu~" << endl;
	cout << "This program can convert area unit between square metres and square feet." << endl;
	cout << "Options (1 to 3) for:\n";
	cout << "(1) Converting a value from square metres to square feet.\n";
	cout << "(2) Converting a value from square feet to square metres.\n";
	cout << "(3) Exit and return to the Program Selection Menu.\n";
	
	cout << "Please input option here:";
	cin >> opt;
	
	switch (opt) {
	case 1:cout << "Please enter a number that you want to convert to square feet from square metres:";
	cin >> UnitA;
	cout << fixed << setprecision(2) << "The square feet unit is " << UnitA*10.764 << ".";
	case 2:cout << "Please enter a number that you want to convert to square metres from square feet:";
	cin >> UnitB;
	cout << setprecision(2) << "The square metres is " << UnitB/10.764 << ".";
	case 3:cout << "Goodbye!";break;
	default: cout << "Wrong input option";
	}
	

	


}

How can I show again the ~Area conversion menu~ and the followings after I convert a number.For example, I choose option 1,I input "1",and it show the square feets is 10.764, and then I want it show again ~Area conversion menu~ and the followings and the user can input other option(1 to 3)???

1.) You need break statements for the cases unless, you intended for it to jump (ex input 1... executes 1,2,3).
2.) Consider a loop?
3.) Adding an exit option when loop implemented?
