Introduction

Welcome to the final project of the Fortran Programming Course! This project is designed to integrate and apply all the concepts and skills you have learned throughout the course. You will be tasked with developing a comprehensive application that demonstrates your proficiency in Fortran programming.

Project Overview

Objective

The objective of this project is to create a comprehensive application that solves a real-world problem or performs a complex task. You will need to:

Design the application architecture.
Implement various Fortran features and modules.
Ensure the application is efficient, maintainable, and well-documented.

Project Requirements

Your application should include the following components:

User Interface: A simple text-based interface for user interaction.
Data Handling: Use of arrays, strings, and derived types to manage data.
File Operations: Reading from and writing to files.
Procedures and Functions: Modular code with subroutines and functions.
Control Structures: Use of loops and conditional statements.
Advanced Features: Implementation of pointers, dynamic memory allocation, and possibly parallel programming.

Project Ideas

Here are a few project ideas to get you started:

Scientific Data Analysis Tool

Description: Develop a tool that reads scientific data from files, performs statistical analysis, and outputs the results.
Features:
- File reading and writing.
- Data storage using arrays and derived types.
- Statistical calculations (mean, median, standard deviation).
- Modular code with subroutines for each calculation.

Simulation of a Physical System

Description: Create a simulation of a physical system, such as a pendulum or a projectile motion.
Features:
- Mathematical modeling of the system.
- Use of arrays to store simulation data.
- Visualization of results (e.g., outputting data to a file for plotting).
- Parallel processing for performance optimization.

Inventory Management System

Description: Build an inventory management system for a small business.
Features:
- User interface for adding, removing, and updating inventory items.
- Data storage using derived types and arrays.
- File operations for saving and loading inventory data.
- Subroutines for each operation (add, remove, update).

Project Development Steps

Step 1: Planning

Define the Scope: Clearly outline what your application will do.
Design the Architecture: Plan the structure of your code, including modules, subroutines, and data structures.

Step 2: Implementation

Set Up the Environment: Ensure your development environment is ready.
Write the Code: Start coding based on your design. Break down the project into smaller tasks and implement them one by one.
Test Regularly: Test each component as you develop it to ensure it works correctly.

Step 3: Optimization and Debugging

Optimize the Code: Look for ways to improve the performance of your application.
Debug: Identify and fix any issues in your code.

Step 4: Documentation

Comment Your Code: Ensure your code is well-commented to explain what each part does.
Write a User Manual: Create a simple guide on how to use your application.

Step 5: Final Review

Test the Entire Application: Perform thorough testing to ensure everything works as expected.
Get Feedback: If possible, have someone else review your application and provide feedback.

Example Project: Scientific Data Analysis Tool

Project Plan

1. Define the Scope

The tool will read data from a file, perform statistical analysis, and write the results to another file.

2. Design the Architecture

Modules:
- main.f90: Main program.
- file_io.f90: File input/output operations.
- data_analysis.f90: Statistical analysis functions.
Data Structures:
- Arrays for storing data.
- Derived types for organizing data.

Implementation

main.f90

program main
  use file_io
  use data_analysis
  implicit none

  ! Variables
  real, dimension(:), allocatable :: data
  real :: mean, median, stddev

  ! Read data from file
  call read_data('input.txt', data)

  ! Perform analysis
  mean = calculate_mean(data)
  median = calculate_median(data)
  stddev = calculate_stddev(data)

  ! Write results to file
  call write_results('output.txt', mean, median, stddev)

end program main

file_io.f90

module file_io
  implicit none
  contains

  subroutine read_data(filename, data)
    character(len=*), intent(in) :: filename
    real, dimension(:), allocatable, intent(out) :: data
    integer :: i, n

    ! Open file and read data
    open(unit=10, file=filename, status='old')
    read(10, *) n
    allocate(data(n))
    do i = 1, n
      read(10, *) data(i)
    end do
    close(10)
  end subroutine read_data

  subroutine write_results(filename, mean, median, stddev)
    character(len=*), intent(in) :: filename
    real, intent(in) :: mean, median, stddev

    ! Open file and write results
    open(unit=20, file=filename, status='new')
    write(20, *) 'Mean:', mean
    write(20, *) 'Median:', median
    write(20, *) 'Standard Deviation:', stddev
    close(20)
  end subroutine write_results

end module file_io

data_analysis.f90

module data_analysis
  implicit none
  contains

  function calculate_mean(data) result(mean)
    real, dimension(:), intent(in) :: data
    real :: mean

    mean = sum(data) / size(data)
  end function calculate_mean

  function calculate_median(data) result(median)
    real, dimension(:), intent(in) :: data
    real :: median
    real, dimension(:), allocatable :: sorted_data

    sorted_data = data
    call sort(sorted_data)
    if (mod(size(data), 2) == 0) then
      median = (sorted_data(size(data)/2) + sorted_data(size(data)/2 + 1)) / 2.0
    else
      median = sorted_data((size(data) + 1) / 2)
    end if
  end function calculate_median

  function calculate_stddev(data) result(stddev)
    real, dimension(:), intent(in) :: data
    real :: stddev
    real :: mean

    mean = calculate_mean(data)
    stddev = sqrt(sum((data - mean)**2) / (size(data) - 1))
  end function calculate_stddev

  subroutine sort(array)
    real, dimension(:), intent(inout) :: array
    integer :: i, j
    real :: temp

    do i = 1, size(array) - 1
      do j = i + 1, size(array)
        if (array(i) > array(j)) then
          temp = array(i)
          array(i) = array(j)
          array(j) = temp
        end if
      end do
    end do
  end subroutine sort

end module data_analysis

Testing and Optimization

Test the application with different datasets to ensure accuracy.
Optimize the sorting algorithm if necessary.

Documentation

Comment each subroutine and function.
Write a user manual explaining how to use the tool.
