manufactures several types of candy. Design a flowchart or pseudocode for the following: a. A program that accepts a candy name (for example‚ “chocolate-covered blueberries”)‚ price per pound‚ and number of pounds sold in the average month‚ and displays the item’s data only if it is a best-selling item. Best-selling items are those that sell more than 2‚000 pounds per month. Answer: A sample solution is as follows: Pseudocode: start Declarations string name double pricePerPound

CheckPoint: Programming Problems Complete the programming problems 1 and 2 as described below. DO NOT COMPLETE THE PROBLEMS FROM THE TEXT For each of the following problems‚ use the top-down modular approach when writing the pseudocode to design a suitable program to solve each problem. Be sure to include an “analysis” for each problem. Note: you need to write 2 separate programs that will handle each problem separately. That means you will also have 2 analyses. Problem 1 Design a program
