So far i have :

but then i have to reverse num and print the square root of that reversed number. I'm lost. I know that I have to use char or array but i'm not even sure how to start.Code:`main(){`

int num;

double s;

int i=0;

printf("Enter 4 digit integer: ");

scanf("%d",&num);

s=sqrt(num);

printf("Square root of %d is: %6.4f \n", num, s);

Anybody can point me in the right direction?

Thanks
