[Need help with my assignment] C++

[benjamin tan]

Hi all pros,
can anybody teach me write this programme in c++???

Problem Statement
Write a simple Mathematics quiz application which has six selections as below:
1) To register number of participants and name
2) To set level of difficulty (level: Beginner or Advanced)
3) To start the quiz (default: Beginner level)
4) To display the scores
5) To show ranking
6) To quit

Your program has to ask the user to key in the following details:
i) An integer (from 1 to 6) representing the program menu selection options.
ii) An integer (from 1 to 5) representing number of participants (maximum 5 participants).
iii) A character representing the level of difficulty: ‘B’ for Beginner; ‘A’ for Advanced.
a. Beginner level: Participants are required to answer as many questions as possible in 60 seconds. Questions involving addition, subtraction or multiplication operation are chosen randomly. The two operands in this level have to be set within 1 to 50 inclusive.
b. Advanced level: Participants are required to answer as many questions as possible in 60 seconds. Questions involving square or square root operation are chosen randomly. The operand for questions involving square ranges from 1 to 30 inclusive. The operand for questions involving square root ranges from 1 to 900 inclusive and must be a perfect square number.

Hints:
- For time, use difftime(time_t, time_t) function and include <ctime> header
- For random number, use rand() and include <cstdlib> header
E.g.
x = rand()%4, will result x from 0 to 3
x = rand()%4 + 1, will result x from 1 to 4
- Use ASCII code to display square root, √ and square, ²

iv) A character (any key) to start the quiz
v) A string representing the response to the quiz question.
User can either key in the answer for the question or key in ‘n’ to skip the question. If an invalid response is detected, user will be asked to re-enter the string until it is valid. The answer for the question will then be converted from string to integer so that it can be compared with the actual answer.
Each correct answer gives the participant 4 marks. 2 marks will be deducted for
each wrong answer. 1 mark will be deducted for each skipped question.
The scores analysis for the participants will then be tabulated and the participants will be ranked from the highest score to the lowest score.

• Loop your program so that the user will be asked to choose from the selection menu above after completing each selection task. Stop the loop only when the user select option 6 to quit.
• When the user quits the loop, display “Bye!”
• Your program must contain at least 8 functions excluding the main function.
• Do not use any global variables.
• Include as well necessary input validations/ error checking in the program.

Due Date: Thursday, 2 September 2010

Submission Requirements
A. Hardcopy:
1. Cover Page
2. Problem Statement
3. Program coding
4. Input and Output ( Include all possible results for all the options )
B. Softcopy of the program (upload to wble.utar.edu.my: e.g. leader_name.cpp) – before 2.00p.m.

Criteria for Grading
• Syntactically correct
• Has input validations/ error checking
• Descriptive variable names
• Proper use of white space, well formatted output
• Proper and consistent indenting
• Correct and descriptive output
• Proper comments
• Complete with requirements
• Original work
Your program should produce an output with the same format as the example shown below.

can anybody teach me write this programme in c++???

Yes. Provided you come to the table with something more than a copy/paste job of your assignment. What have you tried? Which part is stumping you? Can you put together a program that does some of the functions? etc.

[NathanOliver]

What do you have so far?

[asha11]

The exact same questions has been asked to me and I tough time doing the part display scores and ranking..anyone could help me...This is what I have done so far..I dont know whether it is correct or not???
