Output trouble

[ZachyJ]

I am suppose to write a menu based program that is suppose to pick an item off a menu, a side, and a drink. I tried to do as much as I could on my own but I'm stuck. When I run the program, and enter my choices in, it gives me weird numbers. Like: If I input choice 4(Deluxe Mix) and for a side I enter 8 (Cole Slaw) and for drink I enter 15 (orange juice); instead of adding their values to equal 8.7, it outputs the number 14. I feel like I'm forgetting something small, or just I'm completely wrong. -- Thanks in advance!
P.S sorry everything is so spaced out, it helps me see better

There are a number of issues wrong with your program at the moment. Make sure you review how to write switch statements, the format for switches should be

switch(x) {
    case: a
 
    break;
    case: b
    
    break;
    //etc..
}

rewriting switch ruins the purpose of the statement, it's designed to be a better option than using a cluster of if statements.

You're also doing something really wonky here:

price = choice1+=choice2+=choice3

you never initialize choice2 or 3 to zero and also don't use them anywhere in the program, what is the point of these extra two variables? If you want the price to be added on you would say

price += choice1
