/*c program for number decrease triangle*/
#include<stdio.h>
int main()
{
 int num,r,c,sp;
 printf("Enter max number : ");
 scanf("%d", &num);
 for(r=0; r<=num; r++)
 {
   for(sp=r; sp<num; sp++)
       printf(" ");
   for(c=r; c>=0; c--)
       printf("%d",c);
   for(c=1; c<=r; c++)
       printf("%d",c);
   printf("\n");
 }
 getch();
