C++ Exercises: Display the pattern like right angle triangle with number

Sample Solution:-

C++ Code :

#include <iostream>
using namespace std;

int main()
{
   int i,j,rows;
    cout << "\n\n Display the pattern using number starting from 1:\n";
    cout << "------------------------------------------------------\n";
    cout << " Input number of rows: ";
    cin >> rows;
   for(i=1;i<=rows;i++)
   {
	for(j=1;j<=i;j++)
	   cout<<j;
	cout<<endl;
   }	
}

Sample Output:

 Display the pattern using number starting from 1:                     
------------------------------------------------------                 
 Input number of rows: 5                                               
1                                                                      
12                                                                     
123                                                                    
1234

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.
