guys, is there someone that can help me with my coding?

Question

I have a few problems with my coding and have absolutely no idea what to do to fix it. Basically I need to write a BMI calculator that uses 4 functions namely
1. "getData" which prompts and returns a users weight and height.

2. "calcBMi" to calculate the BMI using the formula bmi=weight/(height * height).

3. "displayFitnessResults" to display the bmi and weight status. Bmi < 18.5 - Underweight, bmi >= 18.5 && bmi <= 24.9 - Healthy, bmi >=25 && bmi <= 29.9 - Overweight, bmi >= 30 - Obese.

4. Main function

Answer 1

Of course

Answer 2

I've got a question to 7, how many % is needed for each mark?

Answer 3

Yes. I should end it soon, I've got only 2 fuctions to write.

Answer 4

Okay, I tought it would be easier, but I faced many errors, most of them was caused by SoloLearn's compiler which has too less memory (I suppose). I can show you what I made and I will finish it tomorrow, better compile it in code blocks.

Answer 5

Yeah, that's beacuse I changed code while before, and I'm still getting segmentation fault. I gonna do it on Code Block, so I will fix it faster.

Answer 6

Now it works. Give me a while, I'll send you code.

Answer 7

Why are you unable to untag you form post? If it's beacuse I mentioned you I can just edit it

Answer 8

It was a message to man who deleted his post, not you :D beacuse he was still getting nofications

Answer 9

If you wanna enter every mark separately change getMarks to that:

void getMarks(int (&marks)[6], string subjects[6]){

    for(int i = 0; i < 6; i++){
cout<<"Enter your marks for " << subjects[i] << endl;
        do{
             cin >> marks[i];

        }while(marks[i] < 0 || marks[i] > 100);

    }

}

And i main:

getMarks(marks, subjects);

Answer 10

Everything works, now it's only about changing the look of output.

Answer 11

I changed formula to w(h*h/10000) so you can input height in cm. If you want to enter it in meters remove '/10000' and change 'int' types to 'float'.

Answer 12

You're sure. I corrected it.

Answer 13

On SoloLearn you can enter values only one time, before the whole output.
Normally you could do it like that:
cout<<"enter weight";
cin>>w;
cout<<"enter height";
cin>>h;

Answer 14

Edit fuction getData:

void getData(float &w, float &h)
{
cout << "Please enter your weight in Kilograms: " << endl;
cin >> w;
cout << "Please enter your height in Meters: " << endl;
cin >> h;
}

Then delete this from main:

cout << "Please enter your weight in Kilograms: " << endl;
cin >> w;
cout << "Please enter your height in Meters: " << endl;
cin >> h;

Answer 15

So main should look like that:

int main() {
float weight, height;
getData(weight, height);
float bmi = calcBMI(weight, height);
string fat = displayFitnessResults(bmi);
cout << setprecision(3) << "Your weight is "<< weight << "kg and your height is " << height << "m." << endl <<"Your BMI is "<< bmi << "." << endl << fat;
return 0;
}

Answer 16

For real about 1 year, but I have been starting when i was 13, maybe 14.

Answer 17

Learning is sufficient reward for me ;) Give me only some time

Answer 18

I was learning from polish website about c++ (a few free courses, about libs too), but SoloLearn is good. Beside the lessons you have challenges, quizes etc. so when you know syntax you can learn how to code from the others. It's easier then.
