C final project collegiate level - introduction to C

Final Project CS223 Fall 2015

Due : Tuesday, December 1 at the start of the class

Assignment objectives:

- Gain experience using strings, arrays, functions and their interactions

- Gain more experience using arrays (one/multi dimensional)

- Gain more experience using File Input/Output

- Gain more experience using modular programming (functions)

- Reinforce knowledge of previous programming topics

- Use of structure

- Continue to refine C programming skills by following the C coding standard

- Learn to apply "C" programming to problem solving

Problem Description:

Your spaceship is navigating an asteroid field; you are to design a system that will log and display the distance between your spaceship and the asteroids. Each asteroid has (x, y, z) position in space, where x, y, and z are the distances in kilometers (east-west, north-south, up-down) from your spaceship.

Your program will read a file [login to view URL] that represents the ID and location of each asteroid. The distance between your spaceship and each asteroid is calculated based on asteroid’s X, Y, Z position using the following formula.

√ X2 + Y2 + Z2

This program must be secure. The user must input their name and pin number, if both (name and pin) matches the list you have in a text file on the disk ([login to view URL]), than the user gets access to this program. The program should allow 3 tries for name and password entry, if unsuccessful after 3 tries the program should print a message to the user and terminate.

Program Input/ Requirements

• The name and the pin number of the user

• A file called [login to view URL] which contains names and pin numbers. Example below.

leia 12345

darth 23456

r2d2 34567

solo 45678

jabba 56789

yoda 67890

• Input to the program will be generated using random generator for X, Y, and Z coordinate. Random generator will generate numbers between 1 and 1000 (including 1 and 1000). This data will be stored in a text file called asteroid.txt. Assume the speed of asteroids is 25Km/Sec. There must be at least 10 asteroids’ data in the file. The text data file [login to view URL] has the following format: only the numbers and IDs are in the file not the heading (ID, X,Y,Z)

ID​X​Y​Z

A​600​200​59

​B​999​999​15

​C​100​1000​555

​D​500​202​666

Program output / Requirements

1- Write the following data to a file called [login to view URL], after calculating the distance

A​600​200​59​(whatever the result is)

B​999​999​15​(whatever the result is)

C​100​1000​555​(whatever the result is)

​D​500​202​666

2- Print an alarm message to screen with X, Y, and Z positions of asteroids within a distance of less than 750 km.

For the nearest asteroid, send an alarm message to the console followed by 7 beeps.

The alarm message could look like the following: only two digits after the decimal point.

Warning - Warning - Warning

Nearest asteroid B at ??, ??, ??: ?? km away

Time to impact ??? seconds

asteroid B at at ??, ??, ??: ?? km away

asteroid D at at ??, ??, ??: ?? km away

3- Display a bar chart (character) for distance of the asteroids.

Example (something like below):

​A |****************************

​B |*********************

​C |*************************

​D |*******

​E |************

​F |

Scale appropriately

More requirements, In addition to our standards:

1. The [login to view URL] file can contain at least 10 names and pin numbers.

2. Your program should be able to process the minimum of 10 asteroids.

3. You must use a two dimensional array for the asteroids position data.

4. You must use structure to hold the data for name and ID number when you read the file [login to view URL]

5. The main function must do very little other than calling other functions and passing parameters to those functions.

6. Your program should be modularly designed with functions designed to do one task and one task well.

7. Use of pointers for arrays are encouraged

8. Do not use global variables. Pass data back and forth via parameters or as return values.

9. Make your functions as general as possible so that they can be called more than once if needed.

10. Document your main function as well as every function you write.

11. Use defined constants for ALL constants in your program.

General requirement

1- Following comments must be the first lines of your source code

/* -----------------------------------------------

------------------------------------------------ */

2- Next few line of your source code must be comments describing what this program is supposed to do.

3- The first output (display) must be your name

4- The source code file must include comments documenting the design.

5- Indentation and spacing should be used to make the program readable.

6- Throughout this class (including this program you are not permitted to use the following commands: continue, break, exit, or any library functions that perform similarly
