Trouble with nested repetition

[duhman94]

Hi im working on a program that is meant to output numbers like:
1
12
123
1234
12345

, now i can do that, however, i can't quite figure out how to out put the numbers in this fashion:
5
45
345
2345
12345



this is my current code:

#include <iostream> 
#include <iomanip>
using namespace std;

int main()
{      
        
        
     //Simpler version, does the same thing
     
     for ( int i = 1; i <= 5; i ++ ) 
     {
         for ( int j = 1; j <= i; j ++ )
         {
             cout << j;
         }
             cout << endl;
     }
     cout << endl << endl;
     
     
     
     for ( int i = 1; i <= 5; i ++ ) 
     {
         for ( int j = 1; j <= 5; j ++ )
         {
             cout << j;
         }
             cout << endl;
     }
     cout << endl << endl;
     
    
    

     
         
     
     
      
     
      
      
      
      
      cout << endl << endl;
     system("pause");
     return 1;
}

any advice would be appreciated
