Answer / sunny
Hi Guys,
The answers above are correct but i was wondering if one has to add 5+55+555+.... till 'n'digits then??
Then the answer would be
#include<stdio.h>
#include<math.h>
void main()
{
long int res=0;
int n;
printf("The Maximum Digit(i.e. if youy want result upto 555 then enter '3'):");
scanf("%d",&n);
res= (5*pow(10,(n+1)) - 50 -(45*n))/81;
// VII standard maths
printf("%ld",res);
}
THANX
