Assembly Programs

This repository contains a diverse collection of x86 Assembly Language programs, developed as part of academic learning and exploration of low-level programming. These programs demonstrate fundamental operations, control flow, stack manipulation, string handling, and usage of graphics — all written in MASM/TASM syntax for 16-bit DOS environments.

📚 Contents

🧾 Basic Programs

• Print a single character on screen
• Print your name character by character
• Add two numbers
• Subtract two numbers
• Input two numbers and add them
• Declare variables of different types (DB, DW, etc.) and print them on separate lines
• Print two different strings on different lines
• Print alphabets from uppercase to lowercase or vice versa
• Take user input and compare it with a predefined value
• Print an array using a loop
• Input a string and print it
• Multiply two numbers and display the product
• Divide two numbers and display quotient and remainder

🌀 Stack & String Operations

• Swap two numbers using stack
• Reverse a string using stack

🔁 Pattern & Loop Demonstrations

• Display * patterns using nested loops
• Usage of procedures and macros for modular programming

🎨 Advanced Programs with Graphics

1. 🆘 Morse Code Converter (Graphics + File I/O)

• Accepts user input (A–Z, a–z, 0–9) and converts it to Morse code.
• Rejects invalid characters and prompts for re-entry.
• Supports up to 100 characters in a string.
• Outputs Morse code to a text file.
• Displays a main screen with project title, loading bar, and percentage.
• Allows restarting the converter.

2. 🕹️ Pong Game (Interactive Game)

• Main Menu with 3 options:
  • Singleplayer (2 users)
  • Multiplayer (1 user vs Computer)
  • Exit Game
• First player to reach 5 points wins.
• Option to restart the game.

🛠️ Tools & Environment

• Assembler: MASM
• Platform: DOSBox (16-bit Real Mode)
• Language: x86 Assembly (Intel Syntax)
• IDE Notepad++

🎯 Purpose

This repository was created to:

• Strengthen understanding of Assembly language fundamentals
• Practice low-level memory and stack manipulation
• Build interactive and graphical applications in Assembly
• Serve as a resource for students and hobbyists learning x86 Assembly

📁 Getting Started

• 1. Clone the repository

• 2. Run programs using DOSBox

• 3. Assemble with MASM

    masm program.asm
    link program.obj
    program.exe
