Assembly Graphics and Sound Project

Overview

This project is an assembly language implementation designed for MASM (Microsoft Macro Assembler) in real mode. It consists of two main parts:

1. Sound and Display Effects:

   • Plays a unique sound for each lowercase English letter key pressed.
   • Changes the screen color dynamically.
   • Displays the real-time system clock (hours, minutes, seconds) and updates it every second.

2. Graphics Drawing and Input Handling:

   • Accepts user input commands to draw circles, rectangles, and squares with specified dimensions and colors.
   • Uses BIOS interrupt 10h for pixel-based graphics rendering.
   • Detects invalid user inputs and requests corrected input.
   • Allows users to move shapes using keyboard arrow keys.
   • Supports an exit key to terminate the program.

Features

• Uses real mode assembly programming (MASM).
• Implements sound generation via system speaker.
• Dynamically changes screen colors.
• Draws various geometric shapes using BIOS interrupts.
• Processes user input with validation.
• Provides real-time clock display and updates.
• Supports shape movement with keyboard controls.
• Exits gracefully with a defined exit key.

Installation & Execution

Prerequisites

• MASM 6.11+
• DOSBox (or any x86 emulator supporting real mode)

Steps to Run

1. Clone this repository:

   git clone https://github.com/ppakshad/AssemblyGraphicsProject.git

2. Navigate to the project directory:

   cd assembly-graphics-sound

3. Assemble the program using MASM:

   masm Answer1.asm;
   masm Answer2.asm;

4. Link the object files:

   link Answer1.obj;
   link Answer2.obj;

5. Run the executable:

   Answer1.exe  # Runs the sound and color effect program
   Answer2.exe  # Runs the graphics program

User Commands (For Graphics Program)

Drawing Shapes

• Circle:

  >circle x y r color

• Rectangle:

  >rectangle x y m n color

• Square:

  >square x y m color

Controls

Key	Action
⬆️	Move Up
⬇️	Move Down
⬅️	Move Left
➡️	Move Right
ESC	Exit Program

Notes & Limitations

• This project does not use any external libraries; only BIOS interrupts.
• Ensure you run it inside DOSBox or an appropriate real-mode emulator.
• Input values must be valid numbers; otherwise, the program will request correction.
• The clock update is real-time and refreshes every second.
