Number Patterns Example 16 – C Program
write a c program to display triangle number patterns example shows like below patterns.
1
2  1  2
3  2  1  2  3
4  3  2  1  2  3  4
5  4  3  2  1  2  3  4  5
#include <stdio.h>
#include<conio.h>
void main()
{
    int i, j;
    for(i=1; i<=5; i++)
    {    
     for(j=i; j>1; j--)
      {
        printf(" %d",j);
      }
     for(j=1; j<=i; j++)
      {
        printf("%d", j);
      }         
        printf("\n");
    }
getch();
}The output of number patterns c program is :
1
2  1  2
3  2  1  2  3
4  3  2  1  2  3  4
5  4  3  2  1  2  3  4  5
