Number Patterns Example 21 – C Program

write a c program to display triangle number patterns example shows like below patterns.

1
2  3  2
3  4  5  4  3
4  5  6   7  6  5  4
5  6  7  8  9  8  7  6  5

#include <stdio.h>
#include<conio.h>

void main()
{
    int i, j, k;

    for(i=1; i<=5; i++)
    {    
      k=1;
     for(j=1; j<=i; j++)
      {
        printf("%d", k++);        
      }
      k-=2;
    for(j=k;j>=i;j--)
     {
      printf("%d", k--);
     }
        printf("\n");
    }

getch();
}

The output of number patterns c program is :

1
2  3  2
3  4  5  4  3
4  5  6   7  6  5  4
5  6  7  8  9  8  7  6  5
