In this tutorial we will learn:

  1. How to take input?
  2. How to print results as output in different formats?
  3. Making a small application of Arithmetic operations.

Taking inputs:

Every application must take some inputs otherwise its useless. Taking Inputs form users in Assembly language is quite easy. Simply call the read— procedure from the Kip Irvine’s library.

For reading integer inputs:

This will read an integer as input and store it in eax register temporarily. You can later manipulate this value i.e move it in some other register using the mov instruction or store it in memory variable.

Showing outputs:

For output, type writeint writedec or any other write— procedure from the Kip Irvine’s library.

Small arithmetic operation application:

For making a small application that performs 4 basic arithmetic operations, we used this code:
