Simple Calculator in x86_64 Assembly Language

Description

This program is a simple calculator written in x86_64 assembly language. It allows performing basic mathematical operations on two integers.

Program Structure

The program consists of three sections: .data, .bss, and .text.

• The .data section contains text constants used for displaying messages and formatting the result.
• The .bss section reserves space for three 32-bit integers, which will store the values entered by the user and the result of the operations.
• The .text section contains the actual program code, including input/output handling and mathematical operations.

Usage Instructions

The program prompts the user for two integers and the operation number to perform (1 - addition, 2 - subtraction, 3 - multiplication, 4 - division). After entering the numbers and the operation number, the program returns the result of the operation.

How to Run

To compile and run the program, follow these steps:

1. Copy the above source code into a file with a .asm extension.
2. Compile the code using an assembler, e.g., nasm -f elf64 calculator.asm.
3. Link the code using the ld linker, e.g., ld -o calculator calculator.o.
4. Run the program with the command ./calculator.
