Question

This is subject of C++
Your program should read the file answers.dat. This file contains the name of the student who took the quiz, and his answers for each question. The answers file has the following format:

• The student name is always the first line.
• A student name may or may not have last names. For example, both Elvis Presley and Cher took this class.
• A quiz always has 11 questions.
• There is one answer per line. Each answer is one word and all lowercase.

The correct answers to the quiz questions were:

1. C++
2. for
3. if
4. variable
5. function
6. return
7. array
8. void
9. reference
10. main
11. prototype

Name your program pass1.cpp. Your program should meet the following requirements

1. Define a function that can read the input file answers.dat. This function should not print anything.
2. Define a function that computes the quiz score of the function by comparing the correct answers to the student’s answer. The result should be a percentage between 0 and 100, not a value between 0 and 1. This function should not print anything.
3. Define a function that prints the report as shown in the sample run below. The report format should be exactly the same: alignment, numbers after decimal points, and so on. For incorrect answers, print INCORRECT as shown next to the wrong answers.

The only change is that your name should be printed as the top label to indicate you were the developer.

4. The main() function should create the necessary variables and use the three functions above. The main() function should not print anything.
5. You must include a comment at the top of your .cpp file in this format:

/*******************

Pat Programmer

CSCI 2010 Section 03

Assignment 1

Programmed on Windows 7, Visual C++

This program does …

*******************/

You should obviously change the name to your name, the section to your section, the system to the system you used, and write a real description of the program

NOTE: You should not use pointers in this assignment. It is a review from last semester.

Sample Run

Suppose you have an answers.dat with these contents:

Elvis Presley

C++

for

if

variable

function

cheese

array

robots

reference

main

prototype

When you run your program, the output would be:

!!! Pat Programmer’s Most Excellent Quiz Reporter !!!

Report for Elvis Presley

CORRECT ANS   STUDENT ANS

C++           C++       

for           for       

if            if        

variable      variable  

function      function  

return        cheese        INCORRECT

array         array     

void          robots        INCORRECT

reference     reference

main          main      

prototype     prototype

QUIZ SCORE

    81.82%

Answer 1

Note: Could you plz go this code and let me know if u need any changes in this.Thank You
