Question

Need some help in motorola 68k assembly language.

First, the program will print the programming assignment number, your name, and your class account, all on one line. Your program is going to calculate the day of the week that a user entered number falls on in March 2018. Your program will prompt the user to enter a single number of one or two characters in length. Your program will then print the day of the week that day falls on using the provided strings. If the user enters 3, your program will print “The 3th day is Saturday.” You can assume that all day endings are “th”. Your program will not display additional spaces at the beginning of or in the middle of the string
