C++ - Error C2511: overloaded member function not found in 'BMI' - c++

Question

Got an error on my C++ program. It is likely to be something simple as I have only just started programming.
The error is:
Error 1 error C2511: 'void BMI::getWeight(double)' : overloaded member function not found in 'BMI' c:\users\**********\documents\visual studio 2012\projects\project2\project2\bmi.cpp 40 1 Project2
bmi.h:
#include <iostream>
#include <string>
using namespace std;
#ifndef BMI_H
#define BMI_H
class BMI {
public:
//Defualt Constructor
BMI();
//Overload Constructor
BMI(string, int, double);
//Destructor
~BMI();
//Accessor Functions
string getName() const;
// getName - returns name of paitent

//getHeight - returns height of paitent

#endif
bmi.cpp:

BMI::BMI() {

BMI::BMI(string name, int height, double weight) {

BMI::~BMI() {
}
string BMI::getName() const {
return newName;
}
int BMI::getHeight() const {
return newHeight;
}
double BMI::getWeight() const {
return newWeight;
}
void BMI::setName(string name) {
newName = name;
}
void BMI::setHeight(int height) {
newHeight = height;
}
void BMI::setWeight(double weight) {
newWeight = weight;
}

Answer 1

Ok, when I try to compile the code I see a couple of problems:
The setName(string) function in the .cpp doesn't match anything in the header.
The setHeight(int) function in the .cpp doesn't match anything in the header.
The setWeight(double) function in the .cpp doesn't match anything in the header.
I would try to solve the compilation errors in the order they occur, and then see if you still have a problem with getWeight. I'm assuming that you are seeing the same problems with the undeclared functions that I'm seeing.

Answer 2

The error appears to be telling you that you are trying to call BMI::getWeight() somewhere and you are passing in it a parameter with a double type. This error is a bit perplexing as no such function that matches void BMI::getWeight(double) defined in either the BMI class in the header file or the cpp file. If you have changed the code since you posted it up then please do update and post ALL of the compiler messages. I suspect that you have not posted all of the compiler messages because SetName,setHeight and setWeight are all missing from the BMI class definition. So make sure you add all of those into the BMI class.
Also I think that it's good practice to initialize your data members differently. So instead of:
BMI::BMI(string name, int height, double weight) {
newName = name;
newHeight = height;
newWeight = weight;
}
you should prefer:
BMI::BMI(string name, int height, double weight):
newName(name),
newHeight(height),
newWeight(weight)
{ }
