##
Testing Time Complexity

Well this is my homework question. But it is not graded

I am to find the time complexity of the below

So i came up wtih the following:

Code:

#include <iostream>
using namespace std;
int main()
{
int k = 1;
int n = 0;
cout << "please enter n: ";
cin >> n;
cout << endl << endl;
for (int i = 0; i < n; i++)
{
k = k * 2;
for (int j = 0; j < k; j++)
cout << /*"j = " << j << "\t"*/ endl;
cout << "k = " << k << "\t";
}
return 0;
}

The results are as follows

My question is, what is the figure/number that would go into the third column?

I found out that k = 2^n

but i need to find out T(n)
