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

1
1  2  1
1  2  3  2  1
1  2  3  4  3  2  1

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

void main()
{
    int i, j;
    k=1;
    for(i=1; i<=4; i++)
    {    
     for(j=1; j<=i; j++)
        {  
            printf("%d",j);
        }
        
     for(j=i; j>=1; j--) 
       {
            printf("%d",j);
       }  
    
        printf("\n");
    }

getch();
}

The output of number patterns c program is :

1
1  2  1
1  2  3  2  1
