    owedPrice = type * mileage;


    return 0;

Please don't double post. There is an edit button available for your posts for a reason. You also still didn't tell us what the problem was!

The problem is that it will not run correctly and I do not get switch statements. I am pretty sure that I have the if/else statement correct.

What is the 'per' supposed to mean here? If you wanted to use division, you would use '/'

 case Sub-Compact: .25 per mile;
                    break;

                break;
    case Suv: .75 per mile;

    case Van: 1.00 per mile;

That's not C or C++. It's English. And "Sub-Compact" is not a legal token in C/C++.

Your problem is using the integer carType to store a double.

To counter this problem you can use carType to get the type of the car and for the switch statement. Then use a double variable called carFactor for the calculation.


double carFactor = 0.0;
  
    switch (carType )
    {
        case 1: carFactor = .25;
        cout<< " your choice was a subCompact ";
        break;
        case 2: carFactor = .50;
        cout<< " your choice was a sedan ";
        break;
        case 3: carFactor = .75;
        cout<< " your choice was a suv ";
        break;
        case 4: carFactor = 1.00;
        cout<< " your choice was a van ";
    }
    
    // processing

    if (milesDriven <= 100)
        totalPriceOwed = milesDriven * carFactor;
    else
    {
        additionalMileage = (milesDriven - 100);
        totalPriceOwed =  additionalMileage * (carFactor + .10) + (milesDriven * carFactor);
    }


Take the code you had before and replace the switch statement and the if conditionals with the one I posted above.

        totalPriceowed =  additionalMileage * (carFactor + .10) + (milesDriven * carFactor);
    }


    return 0;

I keep getting errors about the break statements and the case labels aren't within the switch statement.

You forgot the {} brackets for your switch statement.

switch
{
CODE HERE
}

Also, you didn't print out the amount owed.

Well now the program will run but it asks for the user to enter type of car and when I do it skips asking for the number of miles. The question is there but it skips you being able to enter the amount and goes to the total price owed with a big number.

Well, you have to enter 1, 2, 3, or 4 when it asks for carType in your program.

I tried it with a number between 1 and 4 and it works fine.

I'm guessing that you are trying to write out Sub-Compact or Van, etc. It will skip the number of miles because you are giving your program garbage data. It wants and integer, you can't give it a string.

Yes, switch statements only work with ints, feed it ints nao! IT'S HUNGRY FOR INTS!

Sorry, "it wants an integer" made me want to do that. But seriously, print a table with numbered options, have the user type one of the options and then plug that into the switch statement.
