newline loop

#include <stdio.h>
#include <math.h>

int isprime(int n); 

int main(void)
{
int i; 
int count=1; 
printf( "The prime numbers from 1 to 1000 are \n" );
for ( i = 2;i < 1000;i++){
	if (isprime(i) && count%10!=0)
		printf("%d\t",i);
		count++;
	if (isprime(i) && count%10==0) 
		printf("%d\n",i);
		count++;
}}
int isprime( int n )
{
int sroot = sqrt(n);
int i;
for ( i = 2;i <= sroot;i++){
	if (n % i == 0)
		{return 0;}
	}
return 1;
}

i want a newline to be created after every 10th prime number and the if statements for int count do not work. Suggestions?
