Thread: Program using menu selection and subprograms

Menu selection is pretty simple; I'm sure there are tons of examples in the board archives (that are so cleverly hidden away...to get to them, you must use the well-disguised search button. However, I was bored. Here's one more example.

Code:

#include <iostream>
#include <limits>

using std::cout;
using std::endl;
using std::cin;

int menu()
{
	char choice;
	cout << "Here are a few things I might want to do:\n"
		 << "1) Do my homework.\n"
		 << "2) Post my homework on an Internet message board.\n"
		 << "3) Throw away the homework and claim my dog ate it.\n"
		 << "Choose any of the above, or enter 4 to quit." << endl;
	cin >> choice;
	cin.ignore(std::numeric_limits<int>::max(),'\n');
	return choice;
}

void choice1()
{
	cout << "Good luck with your homework!" << endl;
}

void choice2()
{
	cout << "Poor choice; I hope that works out for you." << endl;
}

void choice3()
{
	cout << "Did that ever work?" << endl;
}

int main()
{
	char choice;
	do
	{
		choice = menu();
		switch (choice)
		{
		case '1':
			choice1();
			break;
		case '2':
			choice2();
			break;
		case '3':
			choice3();
			break;
		case '4':
			break;
		default:
			cout << "Try entering a number that's\
				actually on the screen, bonehead." << endl;
			break;
		}
	}
	while(choice != '4');
	return 0;
}

So you dont want to attempt it yourself. How do you think you would go about using a menu. After all it is a selection process and in your case involves characters...

Code:

cout << "Shall I answer this homework question for you, My choices are: \n";
cout << "\nY for Yes\nN for No\nD for do it yourself\n\n"
cin.get(answer);
answer = toupper(answer);
switch(answer)
{
case 'Y' : cout << "Okay";
               break;
case 'N': cout << "Not doing it";
               break;
case 'D': cout << "Go ahead";
               break;
default : cout << "Entered the wrong character";
               break;
}
