Question

1. Your Body Mass Index (BMI) is a measure of your weight relative to your height. The formula can be found here: http://www.whathealth.com/bmi/formula.html (use the Imperial U.S. Method). Write an algorithm in pseudocode to calculate and display a person's BMI accepting as input their height in feet and inches and their weight in pounds. The output of your algorithm should be as follows: a. BMI b. A statement of whether the result is underweight, normal, overweight or obese.

Answer 1

BMI print "BMI Calculator" declare variables float height, weight, BMI print "Enter height in feet and inches" input height print "Enter weight in pounds" input weight height_in_inch - height * 12 (703 * weight) 7 (height_in_inches * height_in_inches) print BMI if (BMI < 18.5); disp('You are underweight') else if ((BMI > 18.5) && (BMI <= 24.9)); disp('You are normal') else if ((BMI >= 25) && (BMI <= 29.9)); disp('You are overweight') else if ((BMI >= 30); disp('You are classified as obese') end

% code to calculate BMI of a person
% formula : BMI = mass(in pound) * 703 / (height in inches)^2
disp("BMI Calculator")
height = input("Enter your height in feet: ")
height_in_inches = 12.*height
weight = input("Enter your weight in pounds: ")
BMI = (weight .* 703) / (height_in_inches.*height_in_inches)
disp(BMI)
if (BMI < 18.5)
disp('You are underweight')
else if ((BMI > 18.5) && (BMI <= 24.9))
disp('You are normal')
else if ((BMI >= 25) && (BMI <= 29.9))
disp('You are overweight')
else (BMI >= 30)
disp('You are classified as obese')
end
end
end
