Harmonic Sum Calculator (Hybrid Assembly, C, and C++)

Welcome to the Harmonic Sum Calculator project! This repository showcases a hybrid programming approach that combines x86 assembly, C, and C++ to create an efficient harmonic sum calculator. The project was developed as part of CPSC 240 Assembly course and demonstrates the integration of different languages to achieve a functional and educational program. The calculator allows the user to input integer N to calculate the harmonic sum to the Nth precision.

The Harmonic Sum is the total sum of the Harmonic Series.

About

In this project, we use a hybrid approach to leverage the strengths of assembly, C, and C++ programming languages:

• Assembly (harmonic.asm): The assembly code performs efficient calculations for the harmonic sum. It provides the core computation logic for the calculator.

• C (statistics.c): The C driver program coordinates the overall functionality of the calculator. It handles user input/output, interacts with assembly and C++ components, and ensures the smooth operation of the calculator.

• C++ (isfloat.cpp and reciprocal_sum.cpp): The C++ code assists in facilitating input validation (checking for floating-point numbers) and computing the reciprocal sum.

Usage

To run the Harmonic Sum Calculator:

1. Ensure you have the necessary toolchains installed (NASM, GCC, and G++).

2. Open your terminal or command prompt.

3. Navigate to the project directory.

4. Run the r.sh script to assemble, compile, and link the program:

   ./r.sh

Execute the generated my.out executable to launch the calculator:

./my.out
