Calculation error

after I put in all my numbers and the result is displayed I get a huge or tiny number. Not sure what the problem is.

#include <iostream>
using namespace std;
int main()
//Declare Variables
int height, age;
double weight, bmr;
char gender;

cout<< "Enter your weight in pounds\n";
cin>> weight;
cout<< "Enter your height in inches\n";
cin>> height;
cout<< "Enter your age in years\n";
cin>> age;
cout<< "Enter male or female\n";
cin>> gender;

if (gender == 'male')
66 + (6.3 * weight) + (12.9 * height) - (6.8 * age);
655 + (4.3 * weight) + (4.7 * height) - (4.7 * age);

cout<< "Your bmr is"<< bmr << "calories\n";

What did you store in bmr?
It looks like you are getting what ever was at the memory location when bmr was initialized.

In these places, you are not assigning bmr a value:
66 + (6.3 * weight) + (12.9 * height) - (6.8 * age);

655 + (4.3 * weight) + (4.7 * height) - (4.7 * age);

EDIT: You are also mixing data types: doubles and ints. And, gender will only accept one character.

You should define gender like this: char *gender;, and then,
use ""'s instead of '''s in the if and else statements.

char gender can store only one character but you are checking that if it is equal to "male" i.e they are four characters.

66 + (6.3 * weight) + (12.9 * height) - (6.8 * age);
you are niether assigning it to any variable nor using it in any other way.better assign to some variable to use it.
All that stuff worked! thanks guys!
