Character Frequency Calculator (Coal Project)

Overview

This character frequency calculator is implemented in x86 assembly language. The program takes a user-inputted string and calculates the frequency of each character. Users can choose to display the frequency in binary, decimal, or hexadecimal format.

File Structure

• cproj.asm: Assembly code file containing the character frequency calculator.
• README.md (this file): Readme file providing information about the program.

Usage

1. Assemble and link the cproj.asm file using an appropriate x86 assembler and linker.
2. Run the resulting executable to input a string and choose the display format.

Procedures

• frequency: Increments the frequency count of a character.
• clearfreq: Resets all character frequencies to zero.
• decout: Displays a decimal number.
• binout: Displays a binary number.
• hexout: Displays a hexadecimal number.

Input

1. The user is prompted to enter a string.
2. The program then prompts the user to choose the display format (binary, decimal, or hexadecimal).

Output

• The program displays the frequency of each character in the chosen format.
• Results are displayed with a colon (:) separator between the character and its frequency.

Termination

• The program terminates when the user chooses to exit.

Additional Notes

• The program uses x86 assembly language and is designed to run on DOS-like environments.
• Ensure proper setup and configuration of your assembler and linker to build and run the program.
