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.

  2. #include
    void main(){
    int i,j,fact;
    for(i=1;i<=300;i++)
    {
    fact=0;
    for(j=1;j<=i;j++)
    {
    if(i%j==0)
    fact++;
    }
    if(fact==2)
    {
    printf("%d",i);
    printf("\n");
    }
    }

    }

  5. initialise i=2 instead of i=1, otherwise 1 also print in prime no series.
