    Hey guys just like to ask a question how i could use the variable drinkType
    to access either hot or cold drinks depending on what they choose in the menu selection.

    To choose 1 or 2 the same function will run but i need it to just execute
    a certain part if they where to choose hot for example. If they choose cold i would need to run only the statements that print the cold and not the hot.

    Both options have to call the same function though

    Iv written a do while in my main to choose either
    1 Hot Drinks Summary
    2 Cold Drinks Summary

    if they press 1 or 2 it suppose to run the function below and print out

    /**************************************************  **************************
    * Menu option #1: Display Summary
    * Allows the user to display a summary of all hot or cold drink categories
    * and items.
    **************************************************  **************************/
    void displaySummary(GJCType* menu, char drinkType)
      /*  CategoryTypePtr currentCat;
        ItemType currentItem;
        assert(menu != NULL);
        currentCat = menu->headCategory;
        while(currentCat !=NULL)
            currentCat= currentCat->nextCategory;
        print the summary of the list*/

    If I am getting you correctly will not a simple if block solve your problem.

    Just pass your choice 1 or 2 to the function and take decisions based on it using plain old if.

    I hope it will solve your problem. If not, then please explain things more clearly so that people here can try to help you.

    [edit] Didn't really read shabbir's answer. Actually he said the same thing.[/edit]
