Write a program to display all prime numbers in the given range. If there are none, display a message "No prime numbers between to ".

#include <stdio.h>

int main(void)
{
int n1, n2, n, cnt = 0, tmp;

printf("\nEnter the range : ");
scanf("%d%d", &n1, &n2);

if(n1 > n2)
{
n = n1;
n1 = n2;
n2 = n;
}
tmp = n1;
while(n1 <= n2)
{
n = 2;
while(n < n1)
{
if(n1 % n == 0)
break ;
n++;
}
if(n1 == n)
{
printf("\n%d is prime", n1);
cnt++;
}

n1++;
}

if(cnt == 0)
{
printf("There are no prime numbers between %d to %d", tmp, n2);
}


return 0;
}
