<Problem 1: 20> Draw a flowchart for the program that will calculate BMI from a height (in inches) and a weight (in pounds). The program will tell the BMI along with advice.
BMI is calculated in the following way.
BMI = weight in pounds x 703 height in inches x height in inches
Give the following advice.
BMI
25.0 and above Exercise more
Less than 25.0 You have a healthy weight
Test your algorithm using the following 2 cases.
<Test1>
height: 67 weight: 120
Outputs are 19.79
You have a healthy weight
<Test2>
height: 67 weight: 200
Outputs are 31.32
Exercise more
<Problem 2: 40 points> Draw a flowchart for the program that will read an unknown number of ages. (0 is a valid age used for a baby.) The user will enter a negative number if there are no more ages to enter. The program will output the average age and youngest and oldest ages. If no ages were entered, display “No ages were entered” (see <Test 4> below).
Hint: Use 2 boxes to store the youngest and oldest ages. What would you put in these boxes at the beginning?
Test your algorithm using a table with the following 4 cases. Make one table for each test. You will have 4 separate tables.
Age Age ≥ 0 Num Total + AgeàTotal Youngest Oldest Avg
<Test 1> 20, 0, 10, 5, -1
Outputs should be 8.75 (average age) 20 (oldest)
0 (youngest)
<Test 2> 100, 105, -5
Outputs should be 102.5 (average age) 105 (oldest)
100 (youngest)
<Test 3> 50, -7
Outputs should be 50 (average age) 50 (oldest)
50 (youngest)
<Test 4> -1
Outputs should be
No ages were entered
<Problem 3: 40 points> Draw a flowchart for the program that will let a teacher enter exactly 5 scores (each score needs to be greater than or equal to zero). The program will output the total and average score. Reject bad inputs from the user. If she enters a negative number, tell her “Invalid score. Enter a score again”.
Test your algorithm using a table with the following 2 cases. Make one table for each test. You will have 2 separate tables.
Repetition# Score Score < 0
<Test 1>
Enter a score: -10
Invalid score. Enter a score: -50 Invalid score. Enter a score: -35 Invalid score. Enter a score: 20 Enter a score: -30
Invalid score. Enter a score: 60 Enter a score: -40
Invalid score. Enter a score: 40 Enter a score: 30
Enter a score: 15
The total score is 165 The average is 33
<Test 2>
Enter a score: 25 Enter a score: 55 Enter a score: 0 Enter a score: 80 Enter a score: 30
The total score is 190 The average is 38
