Objective To learn how to use arithmetic instructions, simple command line parsing, and write basic I/O system subroutines. Textbook Reading (for next homework): Chapter 9: Section 9.1, Section 9.2 Chapter 9: Section 9.4, Section 9.5 Instruction Write a program to make an elementary calculator, displayed on the HyperTerminal connected to the HCS12 board. The calculator rules are:  Input positive decimal numbers only Input maximum three digit numbers only Valid operators are: +, -, *, and / Input number with leading zero is OK Input only two numbers and one operator in between, no spaces Show 'Ecalc> 'prompt and echo print user keystrokes unltil Return key Repeat print user input and print answer after the '=' sign In case of an invalid input format, repeat print the user input until the error character In case of an invalid input format, print error message on the next line: 'Invalid input format' Keep 16bit internal binary number format, detect and flag overflow error Use integer division and truncate any fraction The HyperTerminal display should look something like the following:Ecalc> Ecalc> 123+4        123+4=127 Ecalc> 96*15        96*15=1440 Ecalc> 456@5        456@        Invalid input format Ecalc> 7h4*12        7h        Invalid input format Ecalc> 3*1234        3*1234        Invalid input format ;due to 4th digit Ecalc> 003-678        003-678=-675 Ecalc> 100+999*2        100+999*        Invalid input format Ecalc> 555/3        555/3=185 Ecalc> 7*(45+123)        7*(        Invalid input format Ecalc> 78*999        78*999        Overflow error Ecalc> -2*123        -        Invalid input format Ecalc> 73/15        73/15=4 Ecalc>   Make your program user friendly by giving directions as to how to correctly use your program. You may want to see the Flow Chart of the above algorithm. Also, make your program 'fool-proof', never crash or stop based on wrong user response. You may add other features or decorations. Design the program to start at $3100 and data to start at $3000. Be sure to put much comments so that grader and others can clearly and quickly understand your program. Comments are very important in assembly language programs. Copy your 'main.asm' file to 'cmpen472hw7_YourLastName.asm'. For example, mine will be 'cmpen472hw7_choi.asm' (Do not ZIP your file.) Turn-in your project source code file through Penn State CANVAS. Upload your source code file into the CANVAS Assignment's Homework submission. Be sure to select CMPEN 472 class and correct Homework number, and with correct file name.

Then post what you thought was the most important concept(s), method(s), term(s), and/or any other thing that you felt was worthy of your understanding in each assigned textbook chapter.Your initial post should be based upon the assigned reading for the week, so the textbook should be a source listed in your reference section and cited within the body of the text. Other sources are not required but feel free to use them if they aid in your discussion.Also, provide a graduate-level response to each of the following questions:Discuss the various defenses in contract formation, stating what is required to establish each individual defense, and providing examples of when the defense may be found valid.Sly Salesperson sells cars. While selling a car, Sly Salesperson tells the potential buyer that “this is the best car around. It’s a great car and sips gas.” The car has an average fuel rating. Has Sly Salesperson committed a misrepresentation? Fraud? Why or why not? Does the analysis change if Sly Salesperson says the car get 40 miles per gallon, but in fact the car only gets 30 miles per gallon?2)350 wordsAssigned Readings:Chapter 4.
