The most important part of developing a program/software is the design process. You are required to describe the following characteristics: purpose, input, process, and output of each function and create three test cases, pseudocode and flowcharts for each of the following questions. Note: Each function should have its own flowchart. Please note you are not asked to write and C++ code and pseudocode should not include any C++ elements such as but not limited to semicolons, cout, and cin. Error Detection Suppose you type a 14-digit credit card number into a Web site, but mistype one of the digits of inadvertently interchange two adjacent digits. The website will perform a validation check that always detects the first type of error and nearly always detects the second type of error. The validation check is as follows and will be illustrated with the credit card number 58667936100244. Consider the 1st, 3rd, 5th, 7th, 9th, 11th and 13th digits of the credit card number (in this case 5, 6, 7, 3, 1, 0, 4). Double each number. In this case, the results are 10, 12, 14,6, 2, 0, 8. If any product is a two-digit number, subtract 9. In this case, the results are: 1, 3, 5, 6, 2, 0, 8. Sum the resultant digits (in this case, the sum is 25). Sum together the remaining seven digits from the credit card number. That is. The 2nd, 4th, 6th, 8th, 10th, 12th, and 14th With the credit card number above, we obtain 8 + 6 + 9 + 6 + 0 + 2 + 4 = 35. Add together the two sums. If the result is a multiple of 10, then accept the credit card number. Otherwise, reject it. We accept the credit card number since 25 + 35 = 60. Write a program that performs data validation on a credit card number. It should include 2 functions, one to read in the credit card number and one to validate the card number. At the end print either “Accepted” or “Rejected”.
