Hello,

I would like to make write a program like categorizing based on answers.

I put what I have now.

a=input("Enter your height in cm: ");
b=input("Enter your weight in g: ");
Gender=input("Enter number for your gender 1=male 2=female: ");
BMI=(b/1000)/(a/100)^2;
disp("Your BMI is: " + BMI);
Status=0;
switch Gender
    case 1
        if BMI<20
            Status="Underweight";
            if BMI>=20 & BMI<25
                Status="Regular weight";
                if BMI>=25 & BMI<30
                    Status="Overweight";
                    if BMI>=30 & BMI<40
                        Status="Adiposity";
                        if BMI>=40
                            Status="Severe Adiposity";
                        end
                    end
                end
            end
        end
    case 2
        if BMI<19
            Status="Underweight";
            if BMI>=19 && BMI<24
                Status="Regular weight";
                if BMI>=24 && BMI<30
                    Status="Overweight";
                    if BMI>=30 && BMI<40
                        Status="Adiposity";
                        if BMI>=40
                            Status="Severe Adiposity";
                        end
                    end
                end
            end
        end
    otherwise
        disp("invalid");
end
disp("Your health status: " + Status);

It does not have an error, but it applies only the first "if" which shows "Status=Underweight", and other "if" shows as "Status=0"

I really appreciate if you can solve this problem.

Thanks,

function BMIdetermination()
a=input("Enter your height in cm: ");
b=input("Enter your weight in g: ");
Gender=input("Enter number for your gender 1=male 2=female: ");
BMI=(b/1000)/(a/100)^2;
disp("Your BMI is: " + BMI);
lookup={'Underweight','Regular weight','Overweight','Adiposity','Severe Adiposity'};
if Gender==1
    Status=lookup{find(histcounts(BMI,[0,20,25,30,40,100]))};
else
    Status=lookup{find(histcounts(BMI,[0,19,24,30,40,100]))};
end
disp("Your health status: " + Status);
end
