Create a flow chart for the following:
A. Problem Analysis
The input consists of computer base price (CompPrice), the CPU choice (CPU_choice), the RAM choice (RAM_choice), and the Graphics Card choice (VideoCard_choice). Once the customer has entered a choice of an option, the program will determine the corresponding cost of that option: CPU_cost, RAM_cost, VideoCard_cost.
The only item output is the computer selling price (ComputerPrice). To determine the ComputerPrice, the following computation is: ComputerPrice = CompPrice + CPU_cost + RAM_cost + VideoCard_cost.
B. Program Design
Things the program must do:
1. Input the computer base price
2. Process the various options to compute the additional costs
3. Total all the costs
4. Display the final selling price
The main Module will contain the following submodules:
Compute_CPU_Cost
Compute_RAM_Cost
Compute_VideoCard_Cost
Display_Computer_Price

Pseudocode as follows:
// Computer Price calculator
// Programmer: Christian Gutierrez, University of Maryland University College
// Version 1.0 - November 09, 2013
// This program find out the total price to purchase all the components required to build a state-of-the-art gaming computer from components available on the internet.
// Variables used:
// CompPrice - computer base price
// CPU_choice, RAM_choice, VideoCard_choice - CPU, RAM and Video card options choices
// CPU_cost, RAM_cost, VideoCard_cost - CPU, RAM and the Video card cost once the options // are selected
// ComputerPrice - find outd the total price of the computer.

C. Program Comments and Test Data
The program should run:
// Computer Base Price
CompPrice = 1815.94
// User select CPU, RAM and Video card choice
CPU_choice = "i3770" // selected choice of three options
RAM_choice= "TX8" // selected choice of three options
VideoCard_choice = "V5900" // selected choice of two options
//Base on user option selection from menu the compute formula goes as follows:
CPU_cost = 269.99
RAM_cost = 149.99
VideoCard_cost = 429.99
ComputerPrice = CompPrice + CPU_cost + RAM_cost + VideoCard_cost
ComputerPrice = 1815.94 + 269.99 + 149.99 + 429.99
ComputerPrice = 2,665.91
