3. Commenting: "Each line of assembly code must be documented with a comment! This comment can be terse. For example, "i++" is a perfectly reasonable comment for the line "addi $t1,$t1,1" where register $t1 holds the loop counter i. 4. Commenting: Each region of assembly code must clearly have a **comment block** documenting the overall purpose of that region, along with what values each register holds. You can use your own judgement for a reasonable region size. 5. There are several Assembly Examples that may help you complete this Lab. Lab Submission: 1. Attach source code file(s) Assignment: In MARS, write and test a complete MIPS program that. reads in positive integers, one at a time until the user enters 0. If the integer is not positive, the program should terminate with the message "Invalid Entry"; otherwise the program should print out the names of the digits of the integers, delimited by exactly one space. For example, if the user entered "728," the output would be "Seven Two Eight." Repeat until the user enters a 0 or the program terminates due to an invalid entry. WEE NOTE: It may be helpful to write this code in Java or C++ just to check that it works and to check your answer.
