1. Guessing game in C
Requirements:
- When the program starts, a random whole number, n, is selected where:
n >= 1 and n <= 100
- The user enters a guess and the program displays
? "higher" if the guess is less n
? "lower" if the guess is greater than n
? "correct" if the guess is equal to n
- The game continues until the user enters a correct guess and then the program quits
- When the program quits, the total number of guesses is displayed as the score
2. Screen saver-bouncing ball in Matlab
Requirements:
- When the program starts, the program needs to read the radius of a circle from the user
- You program should then display the circle on the screen in a random location
- The circle continues to move along a random path until it hits the edge of the window
- The circle bounces off the window and the process is repeated indefinitely
- You can get extra marks if multiple circles bounce and for any visual/audio effects (1%)
3. Password checker in Matlab or C
Requirements:
These days, many systems require users to have passwords that meet certain criteria to make them harder to compromise. At Griffith College, your password must be of a certain minimum length (8 characters) and contain upper and lower case letters and at least 1 number.
For this problem, you need to write a function to verify the integrity of a password. The function should have the following formal definition.
function [ output ] = isValidPassword ( password )
Implement the above method to verify that a provided password meets the following criteria:
- Password must be at least 8 characters long
- Password must contain at least 1 number, 1 lowercase letter and 1 uppercase letter
- Password must contain at least 1 non alpha-numeric character from the below list:
o ! @ # $ % ^ & * ( ) [ ] \ | ? /
- Password should NOT contain any character that is not a letter or a number or on the above list.
When you finish the method, write a scrip file and test the function with several examples. You may use a while loop to get the user to type a password and check it as well.
4. Hangman game in Matlab or C
Requirements:
Difficulty: 4
- Must use plots
- The program reads the position of mouse every time the user clicks on the plot and draws a line from the previous and current position of the mouse (assuming that the first line is drawn from 0,0 to the position of the mouse in first click.
- The program displays a corresponding polygon in a window
- There program must allow the user to draw lines until he clicks somewhere close to the origin (0±0.1, 0±0.1)
- After clicking near the origin, your program should calculate the perimeter of the polygon and display it either in the figure or command window.
Tips:
You can easily get the position of mouse using [X,Y]=ginput(1); where 1 is the number of points that you would like to read from the mouse at once
Documentation:
For each question, you need to write a section as follows:
Section 1:
- User manual
- Overall structure and operation of your program
- Incomplete submission only: how far have you completed? What was the main challenge?
Section 2:
Flow chart and pseudo code
Section 3: How? Why?
You need to explain how and why you have designed your program that way. Particularly, explain why you have used if-elseif-else and not if-else, why while loop, why for loop , etc
