Hi, I am looping a 50 sample size.
The output will be: (it display based on the number of underweight students out of 50 which is 8).
Take more milk,protein shakes,rice,meat,nuts and butter
Take more milk,protein shakes,rice,meat,nuts and butter
Take more milk,protein shakes,rice,meat,nuts and butter
Take more milk,protein shakes,rice,meat,nuts and butter
Take more milk,protein shakes,rice,meat,nuts and butter
Take more milk,protein shakes,rice,meat,nuts and butter
Take more milk,protein shakes,rice,meat,nuts and butter
Take more milk,protein shakes,rice,meat,nuts and butter
Is there anyway to make it display only one and together with the total number of students who are underweight?
Thank you in advance. Any opinions are welcome <3
I have attached my code below.
for i=1:50
if BMI(i)<18.5
BMI_status='Underweight';
if BMI_status=='Underweight'
fprintf('Take more milk,protein shakes,rice,meat,nuts and butter\n',BMI_status);
end
else
BMI_status='Normal';
if BMI_status=='Normal'
fprintf('You are healthy!\n',BMI_status);
end
end
end

You could store the data in a variable and use it later. Try this:
count = 0;
for i=1:50
if BMI(i)<18.5
BMI_status='Underweight';
if BMI_status=='Underweight'
count = count + 1;
end
else
BMI_status='Normal';
if BMI_status=='Normal'
fprintf('You are healthy!\n',BMI_status);
end
end
end
if count > 0
fprintf('Take more milk,protein shakes,rice,meat,nuts and butter\n',BMI_status);
fprintf('Total number of Underweight Students is %d',count);
end
