Reference no: EM133105176

Assignment: subroutines and I/O

In this assignment you will write your first simple subroutine. You will also learn how to obtain input from the user. The scanf subroutine from the C standard library can be used to obtain input from users.

Exercises:

Exercise 1. Copy your "hello.s" program into a new file, called "inout.s". Alter the message in such a way that it prints the correct assignment name ("Assignment 2: inout"). Create a subroutine called "inout" and call it from within your main routine right after your message is displayed. At first, your subroutine should simply return immediately. Build and test your program.

Exercise 2. Alter your "inout" subroutine in such a way that it asks the user for a number, increments the number by one and prints the result on the terminal. Build and test your program and save it for later approval.
