C Program to print Number Triangle
Like alphabet triangle, we can write the c program to print the number triangle. The number triangle can be printed in different ways.
Let's see the c example to print number triangle.

#include  
#include
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= 4
   1
  121
 12321
1234321 


enter the range= 7
      1
     121
    12321
   1234321
  123454321
 12345654321
1234567654321
