CEG220: Introduction to C Programming for Engineers – I

Section 2

Project 1: Triangulation

Program Description:

Frequently, you will come across a time when you need to use triangle rules to triangulate a position. There are three circumstances where we can solve for any side or angle: Side Angle Side (SAS), Angle Side Angle (ASA), and Angle Angle Side (AAS). You must write a program that will ask for each case and solve it. You may assume that all the sides of the triangles are of the same units (feet, meters, kilometers, etc.); all the angles are in degrees.

SAS ASA AAS

Program Requirements:

1) Your program must comply with the class programming standard

2) You must handle SAS, ASA, AAS correctly – taking into account issues of units (ie. you ask for degrees, your program must output degrees even though the trig functions take radians)

3) You must submit a hand-written program specification detailing (1) your approach to solving the problem, (2) the algorithm(s) you used, and (3) justifying the data types you have used

Grading Standard:

This project is worth 50 points. Please note that programs that do not compile or do not link will lose all points related to run-time requirements (examples of run-time requirements includes but is not limited to correct run output, handling certain cases adequately, etc.). Grading standard will be followed strictly:

5 points: run output is included at the end of the program, or in a separate file

20 points: hand-written document (program specification)

60 points: handles all three cases properly (20 points each)

15 points complies with programming standard (5 points each)

· adequate comments – clear, concise, useful; not excessive

· well-named identifiers

· follows program specification

Due Date:

This project is due on 9/18 in my mailbox by 5 pm. If your assignment is late – by 5 minutes or 2 days, the penalty is the same (see syllabus).
