    Default Asterisks

    I am trying to write code that prints out asterisks for a given number of sales. For instance, if a companies sales are $1,000 it prints out 10 asterisk, $500 and then 5 asterisks.

    I just not certain how to declare, or use asterisks.


    Thanks in advance!

    Default Re: Asterisks

    basically I have setup the code asking for the total sales for each store, and I know I need to use a loop to print out the asterisks, just not real sure how to do that for each $100 sold.

    Write out how you would do this on a piece of paper - this is your algorithm. Translate that to code using the appropriate control statements, loops, variables, and method calls. Do you have an algorithm? If so post it.

    This is what I have so far...... not sure how to print out the asterisks from this point

    int store1;
    int store2;
    int store3;
    int store4;
    int store5;
    char "*";

    Scanner keyboard = new Scanner(System.in);

    System.out.print("Enter today's sales for store 1: ");
    store1 = keyboard.nextInt();
    System.out.print("Enter today's sales for store 2: ");
    store2 = keyboard.nextInt();
    System.out.print("Enter today's sales for store 3: ");
    store3 = keyboard.nextInt();
    System.out.print("Enter today's sales for store 4: ");
    store4 = keyboard.nextInt();
    System.out.print("Enter today's sales for store 5: ");
    store5 = keyboard.nextInt();

    System.out.print();
    System.out.print("SALES BAR CHART");
    System.out.print("Store 1: " );

    Default Re: Asterisks

    For future reference , and now would be great as well, could you read this for proper code notation?
    http://www.javaprogrammingforums.com...uncements.html

    The first thing I notice is that you have incorrectly declared a char.

    You haven't given your char a variable name. Since it will be an asterisk, why not name it this?

    char asterisk = '*';

    You may also note that when using char's, you surround the character value with single quotes.

    It seems like you are correctly storing the data for all 5 stores; now all you need to do is print out the number of asterisks. Follow copeg's advice, write out the process you would take in your own words (this is called pseudocode), and come up with an algorithm.

    Tip: Say store 1 had 5 sales for today. You would have find a way to print out five asterisks to represent the sales.

    Thanks for that!

    The asterisk is where I am stuck. Sales have to be in increments of $100 and declaring one to equal 100 is where I am having problems.... I am thinking a for loop?

    Or is it possible to say char asterisk = '*' and then somewhere say * = 100; ??

    clearly this is butchered, but I am thinking it should look something like this:

    System.out.println();
    System.out.println("SALES BAR CHART");
    for( char * = 100; int store1 = 0 || *++)
    System.out.print("Store 1: " );
    System.out.print("Store 2: " );
    System.out.print("Store 3: " );
    System.out.print("Store 4: " );

    Read post #4. How you can write code without knowing the algorithm? Psuedocode helps tremendously in doing so

    The above post by kindk12 has been deemed spoonfeeding, and as a result the code removed.

    @whome, I presume if you saw the code posted, then you know the answer. But keep in mind the following: http://www.javaprogrammingforums.com...n-feeding.html And if this is for school, as I suspect it is, copying said code can be considered academic dishonesty.

    yea, I saw and yes it is for a school program, but using the second method was not allowed in my code, therefore irrelevant to what I was asking for.

    Hey again Whome, it really seems like you are "brand new" to programming. I suggest waiting a bit longer before diving in to the unknown (I know how badly that can get).

    I took the initiative last summer, and throughout lots of trial and error, made quite a bit of progress just by learning on my own. I suggest taking a look at this:
    List of Videos for Java

    The following site contains a series of tutorials that will definitely get you on your way to learning more. I really must emphasize that it's best to take your time. If you rush through it and miss a few essential basics... You may end up building up a number of bad habits, and gaps in your core knowledge.

    Hopefully, once learning a bit more, you'll be able to realize your mistakes!

    Thanks for the site Staticity!

    I really enjoy programming, I just wish I understood it better. I will definitely watch the videos though.
