Question

1) Write a program that: program starts; declares and initializes to zero an integer variable score; declares and initializes to zero a float variable total; uses a for loop statement with integer x initialized to 1 going 5 iterations hence x<5 incremented by 0; input from keyboard integer score in range of 0 to 99; print on new line input value; adds score to total; switch x equals 3 break default x++; after exiting the loop calculate the average score; print on new line the average 6 wide to two decimal places and number of iterations; just before ending print on new line “Program finished!” then terminate program.

Answer 1

Below is the complete code as per the requirements. It is well explained inside the code using comments.

#include <iostream>
#include <iomanip>

using namespace std;

// main function
int main()
{
   // declare score variable and initialize it
   int score = 0;

   // declare and initialize the variable total
   float total = 0;

   // loop for 5 iterations
   int x = 1;
   for (; x < 5; x = x + 0)
   {
       // prompt for score and read it
       cout << "Enter the score [0-99]:" << endl;
       cin >> score;

       // add score to total
       total += score;

       // check for the value of x
       switch (x)
       {
       case 3:
           goto end_loop;   // break loop on x = 3
           break;
       default:
           x++;
       }
   }

end_loop:;   // to break the for loop from inside switch

   // calculate average score
   float average = total / x;

   // print average and number of iterations
   cout << "Average: " << setw(6) << setprecision(2) << fixed << average << ", Iterations: " << x << endl;

   cout << "Program finished!" << endl;

   return 0;
}

Below is the sample output:

This completes the requirement. Let me know if you have any queries.

Thanks!
