W2A1-Problem-Solving Techniques In Week 2 lectures, you learned about algorithms, flowcharts, and pseudocodes. In this assignment, you will study the need for algorithms, flowcharts, pseudocodes, and data types in the various phases of program development. Using the South University Online Library or the Internet, further research on the following: Algorithms Flowcharts Pseudocodes Based on your research and readings, answer the following questions: Do you think every program needs all three (algorithms, flowcharts, and pseudocodes) of them? Why or why not? Justify your answer with examples. If you plan to create any two of them for a program, which one would you eliminate? Why? You have read about fundamental data types in your book. Are these data types enough to represent all data, or do you think additional data types are needed? Why or why not? Explain your answer with examples. Looking at the phases of program development, in which phase should the documentation be done? Why?

Auto-graded programming assignments have numerous advantages, but have some challenges too. Students commonly struggle with realizing that example input / output provided in an assignment's specification interleaves input and output, but the program should only output the output parts. If a program should double its input, an instructor might provide this example:  Enter x: 5 x doubled is: 10 Students often incorrectly create a program that outputs the 5. Instead, the program should only output the output parts:  Enter x: x doubled is: 10 The instructor's example is showing both the output of the program, AND the user's input to that program, assuming the program is developed in an environment where a user is interacting with a program. But the program itself doesn't output the 5 (or the newline following the 5, which occurs when the user types 5 and presses enter).  Also, if the instructor configured the test cases to observe whitespace, then according to the above example, the program should output a newline after Enter x: (and possibly after the 10, if the instructor's test case expects that).  The program below incorrectly echoes the user's input to the output.  Try submitting it for grading (click "Submit mode", then "Submit for grading"). Notice that the test cases fail. The first test case's highlighting indicates that output 3 and newline were not expected. In the second test case, the -5 and newline were not expected.  Remove the code that echoes the user's input back to the output, and submit again.  

This assignment takes you into new operations for bits.Ask the user to enter a line of text and then read it in one character at a time. For each character, print the character as a character, its hex value, its decimal value, and its binary value. (One of the philosophic points of this assignment is to remind you that there are no numbers or characters inside the computer; there are just binary bit patterns that have no intrinsic meaning until your program tells the computer how to interpret/manipulate them.) Just to give you a little more work (it's unnecessary to thank me ;-) also count and print the number of bits that are set to 1 in the binary number, and then use that number to determine the “parity”.*Note do 4 spaces for the space and don't do tab.
