Chapter 3: Problem 21

A bowling alley is offering a prize to the bowler whose average score from bowling three games is the lowest. Write a pseudocode algorithm for a program that inputs three bowling scores and calculates and displays their average.

Short Answer

Expert verified
Answer: The sequence of steps in the pseudocode algorithm to calculate the average score of three bowling games is: 1. Input the scores of three bowling games (score1, score2, and score3). 2. Calculate the average by adding the scores and dividing the sum by 3 (average = (score1 + score2 + score3) / 3). 3. Display the calculated average score (PRINT "The average score is ", average).

Step by step solution

01

Input the bowling scores

In this step, we collect the scores of the three bowling games. We will use three variables (score1, score2, and score3) to store the input values. ``` INPUT score1 INPUT score2 INPUT score3 ```
02

Calculate the average

In this step, we calculate the average of the three bowling scores. To calculate the average, we add the three scores and then divide the sum by 3. We will use a variable (average) to store the calculated average. ``` average = (score1 + score2 + score3) / 3 ```
03

Display the average

In this final step, we display the calculated average score. ``` PRINT "The average score is ", average ``` The complete pseudocode algorithm is as follows: ``` INPUT score1 INPUT score2 INPUT score3 average = (score1 + score2 + score3) / 3 PRINT "The average score is ", average ```
