[C++] BMR Calculator - BreShiE - 02-02-2013
After taking a look at one of my college systems, it described a system and formulas to create a BMR (Basal Metobolic Rate) calculator, and I misread the assignment thinking I had to code the system, which I didn't. But I coded the system anyway, so I though I'd share it with you here! I've tested it for both male and female, several heights and weight, and as far as I can tell it runs perfectly! (P.S if anyone knows how to add an icon to console applications, please let me know)
The Code:

Let me know what you think!

I think you deserve the Coder award. Great share man.

Nice of you to post the source

Thanks guys. I'm picking up C++ rather quickly actually. I'm so glad I started learning it in college.

There's just about twice as much code here from what is really necessary.

Not bad, but there is a snippet of code in there that is repeated twice for no real reason. Hopefully by now you've learned to optimize a program such as this. Nonetheless, nice!

lol, I pointed this out months ago.

My mistake, I thought the thread had said it had 0 replies! Next time, I'll be sure to check.

Here's a way you can encapsulate it's functionality:
Code:
#include <iostream>
#include <cstdint>
enum GENDER
{
MALE,
FEMALE
};
struct BMR
{
public:
BMR(GENDER gender) : sex(gender), years(0), weight_kg(0), height_cm(0), last_bmr(0) { }
BMR(GENDER gender, float weight, float height, uint32_t age) : sex(gender)
{
weight_kg = weight;
height_cm = height;
years = age;
last_bmr = 10 * weight + 6.25 * height - 5 * age
+ (gender == MALE ? 5 : -161);
}
uint32_t operator() () { return getBmr(); }
uint32_t last_bmr;
uint32_t years;
float weight_kg;
float height_cm;
GENDER sex;
private:
uint32_t getBmr()
{
return (last_bmr = 10 * weight_kg + 6.25 * height_cm - 5 * years
+ (sex == MALE ? 5 : -161));
}
};
int main()
{
BMR bmr(MALE, 100, 180, 27);
std::cout << bmr() << std::endl;
bmr.weight_kg = 80;
std::cout << bmr() << std::endl;
}Disregarding the user input parsing, there's an example of its usage as well. If you wanted it to say "BMR: {value} or something like that, obviously you'd overload the << operator.

Code-critique, almost a year late.
