    It is an IPM sim for the browser game XNova. However when I compile it I am getting a load of errors. I am used to php telling me the exact error and the line however the error I am getting don't make sense to me. Prehaps someone could help explain.

    Copy and paste from terminal is..

    for example there is an error

    however I don't know what an assignment, pointer or a cast is.

    any help would be great.

    thanks

    ps I have read posts with the poster being crucified for posting because everyone says that he is cheating on there college homework. I don't expect this as I am not asking for some1 to do it for me, just to help explain the errors to me and what I am doing wrong.

    You must be new to C programming --- you are declaring multiple 'item[]'
    Code:
        int item[502],item[503],missiles; 
        int item[401],item[402],item[403],item[404],item[405],item[406],item[407],item[408],item[409],item[410]; 
        int item[401][s],item[402][s],item[403][s],item[404][s],item[405][s],item[406][s],item[407][s],item[408][s],item[409][s],item[410][s];
    ffor example, item[401] is declaring item to be an array of ints of size 401. Then you declare item[402] to be an array of ints of size 402. So you have multiple declarations for the same variable name --- CAN'T DO THAT.

    Declare int item[] one time to be the size you need it to be. If you want to 'initialize' a certain item[], you do it like

    item[400] = 100;

    You really need to understand how to declare variables, especially arrays. Hit the books!

    Unfortunately, everything. You need to start at the beginning and read some tutorials. You can start here.

    Yes, I am new to C, so can you recommend a good tutorial on c arrays?

    I would also look into structures as that seems suited to what you are doing. It would let you do something like:

    TestItem.Name
    TestItem.ShieldCap

    To reference values.

    I would actually recommend reading a good book. Programming in C is probably my favorite.
