Complete Chapter 6, Programming Activity 2: Using "for" Loops. Make sure you study the Programming Activity 6-2 Guidance document.

Programming Activity 6-2 Guidance ================================= For this activity, you are totaling item prices. You must get each item, get its price, and add that price to the total. When you have the final total, you output it in the format specified. Purpose of "for" loop --------------------- You must understand the purpose of the "for" loop in this assignment. The "for" loop is to iterate through the items and update a total. The "for" loop should not be the only thing in the function. It needs appropriate local variables declared BEFORE it begins. That means BEFORE the "for" statement line. You output the total AFTER the "for" loop finishes. That means AFTER its closing brace. That is why local variables, like the total, must be declared BEFORE the "for" loop is entered. If you declared the total variable inside the "for" loop, then it could not be referenced after it. Pseudocode for this assignment ------------------------------ You can find the following in this weeks outline: Calculate a total (using a for loop) (pseudocode) total = 0 // There is no need for a priming read. for (int i = 1; i <= number of items; i++) { read next number // Update read total += number } output total Students who have not taken time to learn about pseudocode, mistakenly think that it is real code and try to use it verbatim. Then, when it does not even compile, they get confused. It is called pseudocode because it is not real, final code. It requires work to turn it into real code. Some fragments of it may match real code. Other parts simply outline what to do. More specifically for 6-2 ------------------------- initialize variables The above pseudocode only shows a total variable. Remember that this is pseudocode. In Java every variable must have a type. You need other variables besides the double for the total. You need a reference to an item of type Item. Another useful variable is a double to store the price of an item. Your for loop must iterate once for each item. Your for loop condition must make use of the parameter numberOfItems, which is automatically passed into the function you are in by the framework. Here is an outline for your for loop body: Get the next item and its price. Update the total with the current item's price. Make the call to animate. After the end of the for loop: Output the results.
