Question

Design the logic for a program that has two parts.

1. The user enters 15 test scores (values between 1-100) that are stored in an array.
2. The program uses the array to compute and output the following statistics
   • minimum
   • maximum
   • average

Write this in pseudocode.

Answer 1

The pseudocode is as follows:

// The variables A (array of size 15), min, max, sum, average are initialized.

Declare A[15], min = 0, max = 0, sum = 0 average = 0

//Read the 15 elements in the array A

for

      read(A[i])

// Let the first element of the array be the minimum and maximum element

min = A[0]

max = A[0]

// For each element in the array, if there exists any element which is less than the

// first element, it becomes the minimum element.

for

      if A[i] < min

          min A[i]

// For each element in the array, if there exists any element which is greater than the

// first element, it becomes the maximum element.

      if A[i] > max

          max A[i]

// Add all the elements of the array A

      sum sum + A[i]

// Increment the counter

      ii+1

// Compute the average by dividing the sum by 15

average = sum/ 15

//Print the maximum, minimum and average.

print max

print min

print average
