#include <iostream>
#include <string.h>
using namespace std;

template <class TypeName>

// function using the template
void printArray(TypeName* arr, int len)
{
    for (int i = 0; i < len; i++) {
        cout << *arr << " ";
        ++arr; // pointing to next element
    }
    cout << endl;
}

// main code/ main function
int main()
{
    // declaring character array
    char chrArr[] = "IncludeHelp";
    //declaring integer array
    int numArr[] = { 10, 20, 30, 40, 50 };

    //printing array elements
    cout << "chrArr: ";
    printArray(chrArr, strlen(chrArr));

    cout << "numArr: ";
    printArray(numArr, 5);

    //passing direct string
    cout << "Hello: ";
    printArray("Hello", 5);
