Print prime numbers between 1-300 using break and continue in c

Print prime numbers between 1-300 using break and continue in c
Definition of prime number:
A natural number greater than one has not any other divisors except 1 and itself. In other word we can say which has only two divisors 1 and number itself. For example: 5
Their divisors are 1 and 5.
Note: 2 is only even prime number.
Example of prime numbers : 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199 etc.
#include <math.h>
#include <stdio.h>
main(){
  int i, j;
  i = 2;
  while ( i < 300 ){
     j = 2;
     while ( j < sqrt(i) ){
         if ( i % j == 0 )
            break;
         else{
            ++j;
            continue;
         }
      }
      if ( j > sqrt(i) )
            printf("%d\t", i);
      ++i;
  }
  return 0;
}
