Number Patterns Example 15 – C Program
write a c program to display triangle number patterns example shows like below patterns.
               5
           5  4
        5  4  3
    5  4  3  2
5  4  3  2  1
#include <stdio.h>
#include<conio.h>
void main()
{
    int i, j;
    for(i=5; i>=1; i--)
    {    
     for(j=1; j<i; j++)
      {
        printf("  ");
      }
     for(j=5; j>=i; j--)
      {
        printf("%d", j);
      }         
        printf("\n");
    }
getch();
}The output of number patterns c program is :
            5
         5  4
      5  4  3
   5  4  3  2
5  4  3  2  1
