scanf

Hello.

When do I need to insert/don't insert & for scanf() in C? Thank you.

int main()
{
    char s1[81], s2[81], s3[81];

    scanf("%s%s%s", s1, s2, s3);

    // If replace scanf() with the expression below, it works too.
    // scanf("%s%s%s", &s1, &s2, &s3);

    printf("\ns1 = %s\ns2 = %s\ns3 = %s", s1, s2, s3);

    return 0;
}

//programming is fun
//
//s1 = programming
//s2 = is
//s3 = fun
