C++, Class: Out-of-line declaration of a member error?

I am trying to create a dynamic array using a class. In my header file I have the following code:

#ifndef DYNAMICARRAY
#define DYNAMICARRAY
#include <iostream>

class Array 
{

public:

    Array(); // Constructor - Initialises the data members
    ~Array(); // Destructor - That deletes the memory allocated to the array
    void addTings (float itemValue); // which adds new items to the end of the array
    float getTings (int index); // which returns the item at the index
    void size(); // which returns the number of items currently in the array

private:

    int arraySize;
    float  *floatPointer = nullptr;
};

#endif // DYNAMICARRAY

And in my .cpp file I have the following code:

#include "DYNAMICARRAY.h"

Array::Array()
{
    floatPointer = new float[arraySize];
}

Array::~Array()
{
    delete[] floatPointer;
}

void Array::addTings (float itemValue);  // Out-of-line declaration ERROR
{
    std::cout << "How many items do you want to add to the array";
    std::cin >> arraySize;
}

float Array::getTings (int index);    // Out-of-line declaration ERROR
{

}

void Array::size()
{

}

I am getting a Out-of-line declaration of a member must be a definition compile error on both of the lines:

float Array::getTings (int index);

and

void Array::addTings (float itemValue);

Does anyone have any idea why? I thought I had linked the header file to the cpp file correctly but obviously not?

Get rid of the semi-colons in the definition of the functions. See below

void Array::addTings (float itemValue);
{
}
float Array::getTings (int index);
{
}

void Array::addTings (float itemValue)
{
}
float Array::getTings (int index)
{
}

You should remove the semicolons in the cpp file.

void Array::addTings (float itemValue);

should be

void Array::addTings (float itemValue)

Correct code is:

void Array::addTings (float itemValue)  // Out-of-line declaration ERROR
{
std::cout << "How many items do you want to add to the array";
std::cin >> arraySize;


}

float Array::getTings (int index)    // Out-of-line declaration ERROR
{

}
