MultiThread Calculator

A multithreaded calculator application written in C that demonstrates the use of threads and parallelism to perform mathematical operations like addition, multiplication, factorials, and more.

---

Features

• Addition: Parallel addition of numbers using multiple threads.
• Multiplication: Parallel multiplication of numbers.
• Factorial Calculation: Calculate the factorial of numbers in parallel.
• Average Calculation: Compute the average of numbers.
• Dynamic Input: Add numbers to the list during runtime.

---

Requirements

• C Compiler: GCC or any C99-compliant compiler.
• CMake: Version 3.10 or higher.
• POSIX Threads: Required for multithreading.

Required Libraries

• pthread: Used for multithreading.

To install required libraries on a Debian-based system (e.g., Ubuntu), use the following command:

sudo apt-get install libpthread-stubs0-dev

For RedHat-based systems (e.g., CentOS, Fedora), you can use:

sudo yum install glibc-devel

Usage

1. Clone the Repository

git clone /~https://github.com/yourusername/MultiThreadCalculator.git
cd MultiThreadCalculator

2. Build the Project

mkdir build
cd build
cmake ..
make

3. Run the Program

./bin/MultiThreadCalculator <thread_count>

• Replace <thread_count> with the number of threads you want to use. For example:

./bin/MultiThreadCalculator 4

4. Follow the Instructions

The program will prompt you to:

1. Enter the number of elements.
2. Enter the numbers.
3. Choose operations (e.g., addition, multiplication, etc.).

Example

./bin/MultiThreadCalculator 4

Input:

Enter the number of elements: 3
Enter the numbers:
Number 1: 2
Number 2: 4
Number 3: 6
Choose operation:
1. Add Numbers
2. Multiply Numbers
3. Calculate Factorial of Numbers
4. Calculate Average
5. Add a Number
6. Exit

Output:

The sum is: 12.00
The product is: 48.00
