Question

In this lab, you complete a partially prewritten C++ program that uses an array.

The program prompts the user to interactively enter eight batting averages, which the program stores in an array. The program should then find the minimum and maximum batting average stored in the array as well as the average of the eight batting averages. The data file provided for this lab includes the input statement and some variable declarations. Comments are included in the file to help you write the remainder of the program.

Instructions

1. Ensure the source code file named BattingAverage.cpp is open in the code editor.

2. Write the C++ statements as indicated by the comments.

3. Execute the program by clicking the Run button. Enter the following batting averages: .299, .157, .242, .203, .198, .333, .270, .190. The minimum batting average should be .157, and the maximum batting average should be .333. The average should be .2365.

GIVEN CODE

#include <iostream>

#include <string>

using namespace std;

int main()

{

   // Declare a named constant for array size here

   

   // Declare array here

   

   // Use this integer variable as your loop index

   int loopIndex;

   // Use this variable to store the batting average input by user

   double battingAverage;

   // Use these variables to store the minimim and maximum values

   double min, max;

   // Use these variables to store the total and the average

   double total, average;

   // Write a loop to get batting averages from user and assign to array

   

      cout << "Enter a batting average: ";

      cin >> battingAverage;

      // Assign value to array

      

   // Assign the first element in the array to be the minimum and the maximum

   min = averages[0];

   max = averages[0];

   // Start out your total with the value of the first element in the array

   total = averages[0];

   // Write a loop here to access array values starting with averages[1]

   

      // Within the loop test for minimum and maximum averages.

      

      // Also accumulate a total of all averages

      

   

       

   // Calculate the average of the 8 batting averages

   

   // Print the batting averages stored in the averages array

   

   // Print the maximum batting average, minimum batting average, and average batting average

   

   return 0;

}

Answer 1

Hi,

Hope you are doing fine. I have written the code as per the requiremnts mentioned and have executed it. The code is clearly explained using comments that have been highlighted in bold. The logic is pretty straightforward and also have a look the executable snippet from code editor and the sample output. You may modify the output as per your requirement (some print stements of output).

Program:

#include <iostream>
#include <string>

using namespace std;

int main()
{

// Declare a named constant for array size here
const int size=8;
// Declare array here
double averages[size];
// Use this integer variable as your loop index
int loopIndex;
// Use this variable to store the batting average input by user
double battingAverage;
// Use these variables to store the minimim and maximum values
double min, max;
// Use these variables to store the total and the average
double total, average;
// Write a loop to get batting averages from user and assign to array
   for(loopIndex=0;loopIndex<size;loopIndex++)
   {
cout << "Enter a batting average: ";
cin >> battingAverage;
// Assign value to array
   averages[loopIndex]=battingAverage;
   }
// Assign the first element in the array to be the minimum and the maximum
min = averages[0];
max = averages[0];
// Start out your total with the value of the first element in the array
total = averages[0];
// Write a loop here to access array values starting with averages[1]
   for(loopIndex=1;loopIndex<size;loopIndex++)
   {
// Within the loop test for minimum and maximum averages.
//checking for maximum
if(averages[loopIndex]>max)
max=averages[loopIndex];
//checking for minimum
if(averages[loopIndex]<min)
min=averages[loopIndex];
// Also accumulate a total of all averages
total=total+averages[loopIndex];
    }
// Calculate the average of the 8 batting averages
//average is given by total/size
average=total/size;
// Print the batting averages stored in the averages array
   cout << "Batting averages stored in averages: \n";
    for(loopIndex=0;loopIndex<size;loopIndex++)
    cout << averages[loopIndex] << "\n";
// Print the maximum batting average, minimum batting average, and average batting average
cout << "Maximum batting average: " << max <<"\n";
cout << "Minimum batting average: " << min <<"\n";
cout << "Average batting average: " << average <<"\n";

return 0;
}
