Write a MIPS program that prompts for and reads in a positive signed 32-bit integer n

INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

Part A

Write a MIPS program that prompts for and reads in a positive signed 32-bit integer n (use the print_sring and read-int syscalls). It should then calculate and print out the binary representation of that integer, one digit at a time, from the most significant to the least bit. Since we know it will not be greater than a 31 bit number (since it is positive integer) you should print a 0 first to make it a full 32 bit binary representation.

For example, if the user entered 3072015 it should look like the following:

Please enter a positive 32-bit integer: 3072015 0000000001011101110000000001111

Part B

Modify your program from part A to add a loop when asking for the integer n and continue to loop until the user enters a 0. If they provide a negative number, you should print an error message and loop again. You will want to print a newline character after each loop to ensure that the output is easy to read.

Part C

Modify your program from part B such that, instead of just printing the digits immeditately to the screen, your program will store the digits (including the leading 0) into a character array and then print that string when you are done processing the number. Since we know it is a 31 bit number (since it is positive), we can define our output array as either .space 33 or .asciiz with a statically assigned 32 character string of zeros (remember: the print_string syscall requires a null terminated character array/string). So the output will be identical as Part A for each number retrieved from the user.

Test your program with several values of n. Provide output for n=1023, 20480 and 30000000

For each MIPS program be sure to use proper documentation to describe what the code is doing. See labs and lecture videos for proper comments and formatting.
