{
event.preventDefault();
var phoneNumber = form.phoneNumber.value;
var userName = form.userName.value;
if(phoneNumber.length!=10)
console.log("Phone Number is Invalid");
if(userName.length<11)
console.log("User Name is Invalid");
}
Explanation:
Kendall should report the email as scam and delete email instead of forwarding it. She should also run her virus protection software as these kind of emails on the Internet are mostly Fraud and can contain virus so the user should avoid them.
Answer:
Following are the missing code to this question:
break;
Explanation:
In the given python code, a method "retry" is defined, that accepts two-variable, that is "operation and attempts" in its parameters, inside the method a for loop is defined that uses the n variable to holds attempt values and define the conditional statement.
- Inside if block, it checks if the operation value is true, it will print a successful attempts values and break the condition, otherwise it will goto else block.
- In the else block, it will print failed attempts values.

Explanation:
223.1.17/24 indicates that out of 32-bits of IP address 24 bits have been assigned as subnet part and 8 bits for host id.
The binary representation of 223.1.17 is 11011111 00000001 00010001 00000000
Given that, subnet 1 has 63 interfaces. To represent 63 interfaces, we need 6 bits (64 = 26)
So its addresses can be from 223.1.17.0/26 to 223.1.17.62/26
Subnet 2 has 95 interfaces. 95 interfaces can be accommodated using 7 bits up to 127 host addresses can represented using 7 bits (127 = 27)
and hence, the addresses may be from 223.1.17.63/25 to 223.1.17.157/25
Subnet 3 has 16 interfaces. 4 bits are needed for 16 interfaces (16 = 24)
So the network addresses may range from 223.1.17.158/28 to 223.1.17.173/28
