How to insert element using template

I have some doubts about my insert method. it is compiling, but with no result )). I presume that it is containing some coding errors. Can you help me resolving this? Thanks in advance.

private:
 T*             elements;
 int            capacity;
 int            nbElements;
 
 template <class T>
void TableDynamic<T>::insert(const T& element, int index)
 {

 int *temp = new int[capacity] ;
 for(int i =0; i<nbElements; i++)
         {
 temp[i] = element;
          }
  delete[] elements;
 int *elem = new int[capacite];

}

>Solution :

I have written some code for you. see if its works for you.

#include <iostream>
using namespace std;

// insert element using template
template <class T>
class TableDynamic
{
private:
    T *elements;
    int capacity;
    int nbElements;

public:
    TableDynamic(int capacity)
    {
        this->capacity = capacity;
        this->nbElements = 0;
        this->elements = new T[capacity];
    }

    void insert(const T &element, int index)
    {
        if (index < 0 || index > nbElements)
        {
            cout << "Index out of range" << endl;
            return;
        }
        if (nbElements == capacity)
        {
            cout << "Table is full" << endl;
            return;
        }
        for (int i = nbElements; i > index; i--)
        {
            elements[i] = elements[i - 1];
        }
        elements[index] = element;
        nbElements++;
    }

    void print()
    {
        for (int i = 0; i < nbElements; i++)
        {
            cout << elements[i] << " ";
        }
        cout << endl;
    }
};

int main()
{
    TableDynamic<int> table(10);
    table.insert(10, 0);
    table.insert(20, 1);
    table.insert(30, 2);
    // print the table
    table.print();

    return 0;
}
