Question

I need help writing c++ code to make this program.

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.

I need to write a program the helps your instructor grade quizzes. The program will read a file containing a single students answers to a quiz. It will compute the student grade on the test as a percentage and then print report.

CSCI-2010 Assignment 1

OBJECTIVES

This assignment will ensure that you have installed Visual Studio

1

, and can submit

assignments correctly in D2L. It will also help you review C++ from CSCI 1010.

Please start early. Let me know as soon as possible if you have problems installing or using

Visual C++ 2013, or trouble finding your .cpp files for submission.

Grading quizzes

Write a program helps your instructor grade quizzes. The program will read a file

containing a single student’s answers to a recently given quiz. It will compute the student’s

grade on the test as a percentage, and then print a report.

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

Answer 1

AS the question suggested I have created the program although i wasn't clear in which function i should print the outputs. so i printed it in the main function. You can change according to the need.OR comment it i will modify it as soon as possible.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
fstream newfile,newfile1;
string name;
string a[11]={"c++","for","if","variable","function","return","array","void","reference","main","prototype"};
std::string& ltrim(std::string& str, const std::string& chars = "\t\n\v\f\r ")
{
str.erase(0, str.find_first_not_of(chars));
return str;
}

std::string& rtrim(std::string& str, const std::string& chars = "\t\n\v\f\r ")
{
str.erase(str.find_last_not_of(chars) + 1);
return str;
}
std::string& trim(std::string& str, const std::string& chars = "\t\n\v\f\r ")
{
return ltrim(rtrim(str, chars), chars);
}
void reading()
{
newfile.open("answere.txt",ios::in);//open a file to perform read operation using file object
newfile1.open("answere.txt",ios::in); // for printing incorrect answeres
}
float quizscore()
{
int c=0,i=0;
//String b[11];
if (newfile.is_open()){ //checking whether the file is open
string tp;
getline(newfile,tp);
name=tp;
while(getline(newfile, tp)){ //read data from file object and put it into string.
std:: string x=tp;
trim(x); //trimming the string to get the string without any newline character
if(x.compare(a[i])==0)
c++;
i++;

}
//
return (c);
newfile.close(); //close the file object.
}
}
void print()
{
string tp;
int i=0;
getline(newfile1,tp);
while(getline(newfile1, tp)){ //read data from file object and put it into string.
std:: string x=tp;
trim(x); //trimming the string to get the string without any newline character
if(x.compare(a[i])!=0)
cout<<x<<" Incorrect";
i++;
}
newfile1.close();
  
}
int main(){
reading();
float a=quizscore();
cout<<name;
cout<<"\n"<<(a/11)*100<<"%"<<"\n";
print();
return 0;
  
}

OUTPUT:
