Noob C++ Question.

[Skyline34]

I was wondering what the code would be for a number selection menu, such as:

Spoiler for Example:

1. Red
2. Green
3. Blue
4.Yellow

Please choose a number:

Then once a particular number is selected, it should display the chosen option as something like "You chose the colour Red" printed underneath.

Sorry for the noob question, I've literally only just started learning C++ about 3 days ago and I'm just learning the basics at the moment.

Much obliged!

Well I only know very basic C++ in a command prompt window but I would get it to print the options, then ask for an input and then use an if to check the answer. My syntax might not be correct because I haven't used C++ alot bu here it goes:

string answer;

cout << "Please choose an option" << endl << " 1. Red" << endl << "2. Green" << endl << "3. Blue" << endl << "4. Yellow" << endl << "Choice:";

cin >> answer;

if (answer == 1)
    cout << "You chose Red";
elseif (answer == 2)
    cout << "You chose Green";
elseif (answer == 3)
    cout << "You chose Blue";
elseif (answer == 4)
    cout << "You chose Yellow";
else
    cout << "Please enter a valid choice";

Then at the end you could have a loop to loop back to the list if they enter a wrong number for validation ^_^

Hope that helps!

Edit, if I remember correctly the program will close instantly after the user input number and it has checked it so you may need to get it to wait for another input. So like make it ask if the user wants to exit and if they press Y then do

return 0;

and if not then loop back to the beginning of the program.

That's great, I'll give it a shot now, thanks very much!

Tell me how it goes

Make sure you #include <string> in that example. However, I wouldn't suggest using a string, because that code won't work with just a string. Change the line that says "string answer" to "int answer".

Also, I would suggest doing a while loop around it, since it's a menu. Dunno, that's what it sounded like you wanted to do

[FranzH]

Oh yeah >.< I have no idea why I used string...

Yes, that's right.

OK, I got it all sorted except for a single error:

error C2143: syntax error : missing ')' before 'constant'
Error executing cl.exe.

You need to put a ' ) ' somewhere.. look for the line number :l

[Skyline34]

OK cheers.

EDIT: Brilliant! Thank-you so much FranzH and Hardrive!

[Hardrive]

No problem, glad we could help

Actually, one more little question.

How can I get it to loop back to the user prompt after an option has already been chosen?

Thanks
