Program Plan Intro

a.

Top-down design for calculating the average of ten test scores:

From the problem 54,

Assign value to the given variables.

Perform loop iteration for 10 times.

Get the input from user.

Compute the sum of 10 test scores.

Increment the value of counter.

Finally, find the average of 10 scores.

Example:

The example code for calculating average of ten scores is given below:

//Initialize count to 0

Set count to 0

//Initialize total to 0

Set total to 0

//Performs iteration for 10 times

WHILE (count < 10)

    //Read the scores

    Get mark

    //Compute sum of test score

    Set total to total + mark

    //Performs increment for count

    Set count to count + 1

//Print the result of average

Set average to total/10

Explanation:

The above code is used for calculating the average of ten scores using “WHILE” loop. In “WHILE” loop, the addition will perform until the score become greater than “10”.
