Trying to make a quiz with switch

ruroni24 (20)
I was trying to make a quiz with a switch statement...but I realize that it's going to take a lot of work because you will have to paste the same questions over and over again as seen in the code. It's not even nearly finished yet and I'm trying to let the user answer each questions by inputting a number. Is there any way to make this shorter besides pasting the questions again and again? Besides switch, can while loop method make this easier? Thanks in advance.

Hi ruroni24

Friend, you have the wrong concept about switch statements. That's not how they work.
Think of a switch statement like an if/else staement.

1

if (x == 1){
cout << "one";}

else {if (x == 2)
cout << "two";}

else {if (x == 3)
cout << "three";}


You can write this as a switch statement, which is somewhat more readable:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
 
switch(x) {
case 1:
cout << "one";
break;

case 2:
cout << "two";
break;

case 3:
cout << "three";
break;

default:
}
}


So a switch statement could look a little more like:

1

Now to answer your other question, there are many approaches to solve your problem. You could read questions in from a text file... make an array, read your questions from a list... but let's stick to the basics for now...

You could use the direct approach...

    if (choice!=1)
    {
        cout << "Sorry, you are incorrect."<<endl;
    }
    else
    {
        cout << "Way to go!" << endl;
        score++;
    }
    cout << "What datatype do you need to use when you're dealing with numbers that has decimals?" << endl;

    cin >> choice;

    if (choice!=3)
    {
        cout << "Sorry, you are incorrect."<<endl;
    }
    else
    {
        cout << "Way to go!";
        score++;
    }
    return 0;
}



or the function approach...
