To Print Number Triangle

Write a C Program to Print Number Triangle

Program:
 
 #include<stdio.h>  
 #include<stdlib.h> 
    int main()
    { 
      int i,j,k,l,n;   
    system("cls"); 
    printf("Enter the range=");   
    scanf("%d",&n);   
    for(i=1;i<=n;i++)   
    {   
    for(j=1;j<=n-i;j++)   
    {   
    printf(" ");   
    }   
    for(k=1;k<=i;k++)   
    {   
    printf("%d",k);   
    }   
    for(l=i-1;l>=1;l--)   
    {   
    printf("%d",l);   
    }   
    printf("\n");   
    }   
    return 0; 
    } 

Output:

Enter the range=
6
     1
    121
   12321
  1234321
 123454321
12345654321
