Introduction

In my last semester of college, I decided to take a class in Fortran programming just for fun (because who really uses Fortran anymore). The following is a collection of the projects I completed during said class; they range from simple I/O programs to data structure manipulation programs. Documentation for these programs is also provided where available. All programs were compiled using Absoft's Fortran compiler for Windows, and as such I can only guarantee successful compilation on that platform. If you've had success or failure with other compilers, please send me a note regarding it.

I'm mainly making this code available because I was appalled by the lack of Fortran examples there are on the web. If you need further help with the language, I'd recommend obtaining a copy of the Fortran 90 Handbook (ISBN 0070004064); it's particularly useful when trying to figure out the archaic I/O and formatting options.

Projects

• Arithmetic #1
  Files: Code
  Simple program that adds two numbers then outputs
  
• Arithmetic #2
  Files: Code
  Simple program that adds and subtracts two numbers then outputs
  
• Pythagorean Triples
  Files: Code
  Calculates Pythagorean Triples from input given
  
• Triangle Perimeter and Area
  Files: Code
  Calculates triangle perimeter and area from input given
  
• Triangle Validity and Typing
  Files: Code
  Determines from given input whether a triangle is valid or not and, if so, what its type is (i.e. equilateral, isosceles, or scalene)
  
• Fibonacci with Do Loops
  Files: Code
  Outputs X number of terms in the Fibonacci Sequence
  
• Fibonacci with Do Loops continued
  Files: Code
  Same as the last program except that output is formatted and also contains the ratio between two terms
  
• First 10 Partial Sums of 1/k!
  Files: Code
  Outputs the first ten partial sums of the series 1/k! (1 divided by k factorial) with formatting
  
• Multiplication and Division Formatting
  Files: Code
  Outputs the product, quotient, and remainder of the given input with heavy formatting
  
• Bacterial Growth
  Files: Code
  Calculates the population of bacteria given a certain starting count and growth rate
  
• Student Record GPA Calculator with File I/O
  Files: Code
  Reads a data file of student course records and writes a file with calculated GPA
  
• Round Function
  Files: Code
  Uses a custom round function to output some rounded test numbers
  
• Prime Test Function
  Files: Code
  Tests if the given input number is a prime number using a custom function
  
• Perfect Square Test Function
  Files: Code
  Tests if the given input number is a perfect square using a custom function
  
• L-Grid Path Counter
  Files: Code | Doc
  Recursively finds the number of paths through an L-shaped grid (square grid with an area removed from the upper right) from the upper left to the bottom right
  
• Drunkard's Walk
  Files: Code | Pseudo-code | Doc
  Calculates several statistics for X runs of the Drunkard's Walk algorithm
  
• Shell Sort
  Files: Code | Doc
  Creates a random array of numbers and then uses a shell sort subroutine to sort them
  
• Magic Square
  Files: Code
  Uses a recursive function to generate a Magic Square
  
• Angle Class
  Files: Test Program | Class Module | Doc
  Tests a class (or the best equivalent to a class in Fortran) for working with angle data, which includes operator overloads and constructors
  
• Random Binary File
  Files: Main Program | Random Number Module | Doc
  Writes an array of random numbers to both a text and binary file
  
• Random Binary File Reader
  Files: Code | Doc
  Outputs every 100th record from a binary file (typically created with the previous program)
  
• Random Binary File Search
  Files: Code | Doc
  Looks for records in a binary file that match the given input
  
• Queue Class
  Files: Test Program | Class Module | Doc
  Tests a class that implements a queue--uses pointers, of course
  
• Huffman Encoding/Decoding
  Files: Source Archive | Library Module | Doc
  A series of test programs that call subprograms in a library module to perform the various steps of Huffman Encoding: counting the number of character occurances, building a tree, encoding, and decoding. (Unfortunately, the decoding portion wasn't completed due to end-of-semester time constraints.)
