code check: BMI Calculator

[whatthebobo]

I have an assigment where I am to create a program to calculate BMI. I wrote the program and would like to have someone check it to see if there are any mistakes I need to correct.

//Declare variables
    double weight, height, bmi = 0;

    //Prompt user for weight in pounds
    cout << "Please enter your weight in pounds:";
    cin >> weight;

    //Prompt user for height in inches
    cout << "Please enter your height in inches:";
    cin >> height;

    //Display weight and height back to the user
    cout << "This is the weight that you have entered:" << weight << endl;
    cout << "This is the height that you have entered:" << height << endl;

    //Calculate BMI of user
    bmi = ( weight * 703 ) / ( height * height );

    //Display the BMI to user
    cout << "Your BMI is: " << bmi << endl;

    //Display the descriptive word that corresponds to their BMI value

    //If bmi is less than 18.5 classify as underweight
    if ( bmi < 18.5 )
        cout << "You are classified as underweight." << endl;
    //If bmi is 18.5 or greater, but less than 25 then classify as normal
    else if ( bmi >= 18.5 && bmi < 25 )
        cout << "You are classified as normal." << endl;
    //If bmi is 25 or greater, but less than 30 then classify as overweight
    else if ( bmi >= 25 && bmi < 30 )
        cout << "Your are classified as overweight." << endl;
    //If bmi is 30 or greater then classify as obese
    else if ( bmi >= 30 )
        cout << "You are classified as obese."<< endl;

    return 0;

I have used 'build' and 'debug' on visual basic studio to check and it works but I would like another check for it since it is a project grade.
