Cis programming – relational (20 points) description: in this assignment, you will develop a c++ program to decide which apartment to rent. develop a program to choose whether you can afford to live on the river, close to the river, or far from the river. the general rule on how much you can afford for rent and utilities is 40% of gross income. let’s assume utilities are $50 a month. if you cannot afford downtown, then calculate how many roommates you would need to live downtown.

Write a new lc-3 trap subroutine (i.e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i.e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e.g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e.g. b0000 0000 0000 0111 =
