Printing right-aligned triangle with descending numbers

[claivin]

I'm trying to figure out how to create output which looks like this.

   1
  21
 321
4321

This is the code I have right now. 'base' is user-defined.

int main()
{
   int base;
   cin >> base;

void displayPatternC(int base)
{
   cout << "\n***PATTERN C***\n";
   for(int height = 0; height < base; height++)
   {
      for(int count = base; count > height; count--)
      {
         cout << " ";
      }
      for(int count2 = 1; count2 <= height+1; count2++)
      {
         cout << count2;
      }
      cout << endl;
   }
}

Which results in:

    1
   12
  123
 1234

Count2 in your second for loop is incrementing, and you're outputting it as it does so. You want this to decrement like your first count.

ah okay.

I rearranged some variables and got it to work.

void displayPatternC(int base)
{
   cout << "\n***PATTERN C***\n";
   for(int height = 0; height < base; height++)
   {
      for(int count = base; count > height; count--)
      {
         cout << " ";
      }
      for(int count2 = height; count2 >= 0; count2--)
      {
         cout << count2+1;
      }
      cout << endl;
   }
}

Thank you!
