C++ Exercises: Display the n terms of odd natural number and their sum

Sample Solution:-

C++ Code :

#include <iostream>
using namespace std;

int main()
{
    int i, n, sum = 0;

    cout << "\n\n Display n terms of odd natural number and their sum:\n";
    cout << "---------------------------------------------------------\n";
    cout << " Input number of terms: ";
    cin >> n;
    cout << " The odd numbers are: ";
    for (i = 1; i <= n; i++) 
    {
        cout << 2 * i - 1 << " ";
        sum += 2 * i - 1;
    }
    cout << "\n The Sum of odd Natural Numbers upto " << n << " terms"; 

" << sum << endl";
}

Sample Output:

Display n terms of odd natural number and their sum:                  
---------------------------------------------------------              
 Input number of terms: 5                                              
 The odd numbers are: 1 3 5 7 9

Which is faster: Stack allocation or Heap allocation

Stack allocation is much faster since all it really does is move the stack pointer. Using memory pools, you can get comparable performance out of heap allocation, but that comes with a slight added complexity and its own headaches.

Also, stack vs. heap is not only a performance consideration; it also tells you a lot about the expected lifetime of objects.
