Arrays C++

#include <iostream>

using namespace std;

int main()

{

      int   tests[6]; // array declaration

      int   sum = 0;

      float avg;

      //input test scores

      cout << " Enter " << 6 << " test scores: " << endl;

      for (int i = 0; i < 6; i++)

      {

            cout << "Enter Test " << i + 1 << ": ";

            cin >> tests[i];

      }

      return 0;

}   

  1. Type in the above program as array1.cpp. Compile and run. Draw a picture showing what the array looks like in memory.
  2. Add code to print the first test score. Add the following comment://2. Print the first test score
  3. Add code to print the last test score. Add the following comment://3. Print the last test score
  4. Add the code to print all of the test scores. Add a comment: //4. Print all scores
  5. Add code to sum the test scores. Print the sum. Add a comment: //5. Sum all scores
  6. Add code to calculate and print the average test score. Add a comment: //6. Calculate the average
  7. Now add code so an average calculation takes place in a function. Add the following function and the appropriate call to output the average a second time (add a comment: //7). You will also need to add a prototype. Run. Copy and paste the code and output you have up to now in a word document.

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

float CalcAvg(int tests[], int numTests/* must be > 0 */)

{

      int sum=0;

      for (int i = 0; i < numTests; i++)

      {

        sum = sum + tests[i];

      }

      avg = (float)sum/numTests;

     return avg;

}

  1. Submit your program and output from after #7.

Answer #1

Please find the code below:::

#include <iostream>
using namespace std;
float CalcAvg(int tests[], int numTests/* must be > 0 */);
int main()

{

   int tests[6]; // array declaration

   int sum = 0;

   float avg;

   //input test scores

   cout << " Enter " << 6 << " test scores: " << endl;

   for (int i = 0; i < 6; i++)

   {

       cout << "Enter Test " << i + 1 << ": ";

       cin >> tests[i];

   }


   //Add code to print the first test score. Add the following comment://2. Print the first test score
   cout<<"The first test score : "<<tests[0]<<endl;


   //Add code to print the last test score. Add the following comment://3. Print the last test score
   cout<<"The last test score : "<<tests[5]<<endl;


   //Add the code to print all of the test scores. Add a comment: //4. Print all scores
   cout<<"All scores"<<endl;
   for(int i=0;i<6;i++){
       cout<<tests[i]<<endl;
   }

   //Add code to sum the test scores. Print the sum. Add a comment: //5. Sum all scores
   for(int i=0;i<6;i++){
       sum+=tests[i];
   }
   cout<<"Sum of all scores : "<<sum<<endl;


   //Add code to calculate and print the average test score. Add a comment: //6. Calculate the average
   float average = sum*1.0/6;
   cout<<"The average of all scores : "<<average<<endl;


   //Now add code so an average calculation takes place in a function.
   //******************************************************
   float average2 = CalcAvg(tests,6);
   cout<<"The average calculation using function : "<<average2<<endl;


   return 0;

}

float CalcAvg(int tests[], int numTests/* must be > 0 */)

{

   int sum=0;
   float avg;
   for (int i = 0; i < numTests; i++)

   {

       sum = sum + tests[i];

   }

   avg = (float)sum/numTests;

   return avg;

}
