Question

Create a C++ program to :

1. Prompt user for seven test score
2. Store the scores into an array
3. Print the array before and after sorting
4. Print the test average
5. Convert the average to letter grade
6. Search for a test score 90, using linear search
   1. Print, if test score 90 was found and at what position
7. Add Comments

SEPARATE THE FILES INTO 3 : header.h, functions.cpp, main.cpp

Answer 1

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

// header.h

#ifndef HEADER_H
#define HEADER_H

class Test
{
public:
void readScores();
void printScores();
void sort();
double calcaAvg();
char findGradeLetter(double avg);
int search(int score);
private:
// Declaring variables
static int SIZE;
int scores[7];
};
#endif

============================

// functions.cpp

#include <iostream>
using namespace std;
#include "header.h"

int Test::SIZE=7;

void Test::readScores()
{
for(int i=0;i<SIZE;i++)
{
cout<<"Enter Score in Test#"<<(i+1)<<":";
cin>>scores[i];
}
}
void Test::printScores()
{
for(int i=0;i<SIZE;i++)
{
cout<<scores[i]<<" ";
}
cout<<endl;
}
void Test::sort()
{
//This Logic will Sort the Array of elements in Ascending order
   int temp;
   for (int i = 0; i < SIZE; i++)
{
for (int j = i + 1; j < SIZE; j++)
{
if (scores[i] > scores[j])
{
temp = scores[i];
scores[i] = scores[j];
scores[j] = temp;
}
}
}
}
double Test::calcaAvg()
{
double sum=0;
for(int i=0;i<SIZE;i++)
{
sum+=scores[i];
}
return ((double)sum)/SIZE;
}
char Test::findGradeLetter(double average)
{
char gradeLetter;

   if (average >= 90 && average<=100)
gradeLetter = 'A';
else if (average >= 80 && average < 90)
gradeLetter = 'B';
else if (average >= 70 && average < 80)
gradeLetter = 'C';
else if (average >= 60 && average < 70)
gradeLetter = 'D';
else if (average < 60)
gradeLetter = 'F';
return gradeLetter;
}
int Test::search(int score)
{

for(int i=0;i<SIZE;i++)
{
if(scores[i]==score)
{
return i;
}
}
return -1;
}

=================================

// main.cpp

#include <iostream>
using namespace std;
#include "header.h"
int main()
{

Test t;
t.readScores();
cout<<"_____ Displaying test scores ____"<<endl;
t.printScores();
cout<<"_____After Sorting Displaying test scores ____"<<endl;
t.sort();
t.printScores();
double avg=t.calcaAvg();
char gradeLetter=t.findGradeLetter(avg);
cout<<"Grade Letter :"<<gradeLetter<<endl;
int indx=t.search(90);
if(indx!=-1)
{
cout<<"90 is found in the array at position "<<(indx)<<endl;
}
else
{
cout<<"90 is not found in the array"<<endl;
}
return 0;
}
