    Cool problem finding symbol

    So, I was writing some code to figure out what's wrong with the code. I want to assign each mealcode a price.

    Here is my code:

     
    if ((request.contains("no beef") || request.contains("chicken")) && !(request.contains("child")))
        mealcode = 1;
        while (mealcode == 1)
            cost = 1.75;
    else if (request.contains("beef") && !(request.contains("child")))
        mealcode = 2;
        while (mealcode == 2)
            cost = 2.08;
    else if (request.contains("vegetarian"))
        mealcode = 3;
        while (mealcode == 3)
        cost = 2.14;
    else if ((request.conatins("child") && !(request.contains("vegetarian"))))
        mealcode = 4;
        while (mealcode == 4)
        cost = 0.98;
    else
        mealcode = 0;

    I get quite a few errors, including "cannot find symbol" and things that are a little more vague like "else without if" even though I gave each else an if as far as I could tell.

    All help appreciated, ghostheadx

    I suggest putting this into an SSCCE so we can compile it ourselves. This snippet leaves out a lot of valuable information that we need to answer the question. Also, list the errors you're getting- take them one at a time.

    Also also, always use curly braces and proper indentation with your if statements and loops.

    mealcode = 1;
        while (mealcode == 1)
            cost = 1.75;
    Think very carefully about what this code is doing.

    Alright, I guess that's just an infinite loop. Here's my new code:

     
    meals[1] += meals[0]/2;
    meals[2] += meals[0]/2;
    meals[1] += meals[0]%2;

    I'm trying to split a[0] equally between "Chicken-based adult" and "Beef-based adult."
    And if it's not an even number then I want to make "Chicken-based adult" be one more than "Beef based adult."

    Do you mean split each element of the array a[] as you've described, not just a[0]? If so you could do something like the elementary approach I've outlined below. There are more clever ways to accomplish the same thing, but this explains the logic most simply:

    1. determine if a[i] is even
    1.a if even, split the value evenly between chicken and beef
    1.b if not even, subtract one and split the result evenly between chicken and beef, then increase chicken by 1.
