How to make my custom type to work with “range-based for loops”?

Question

Like many people these days I have been trying the different features that C++11 brings. One of my favorites is the \"range-based for loops\".

I understand that:

Here, I am sharing the simplest example of creating custom type, that will work with "range-based for loop":

#include
using namespace std;

template
class MyCustomType
{
private:
    T *data;
    int indx;
public:
    MyCustomType(){
        data = new T[sizeOfArray];
        indx = -1;
    }
    ~MyCustomType(){
        delete []data;
    }
    void addData(T newVal){
        data[++indx] = newVal;
    }

    //write definition for begin() and end()
    //these two method will be used for "ranged based loop idiom"
    T* begin(){
        return &data[0];
    }
    T* end(){
        return  &data[sizeOfArray];
    }
};
int main()
{
    MyCustomType numberList;
    numberList.addData(20.25);
    numberList.addData(50.12);
    for(auto val: numberList){
        cout<

Hope, it will be helpful for some novice developer like me :p :)
Thank You.
