Why is the len ( ) function useful when using a loop to iterate through a stack? a. the len ( ) function will print the elements of the stack. b. the len ( ) function will run with each iteration, printing the element number each time. c. the len ( ) function will tell the program the number of elements in the stack. d. the len ( ) function will remove the duplicate elements in the stack.

C

Explanation:

The len() function will basically tell the number of elements in the stack. You can say that len() will give us the lenght of the stack , how many elements have been added to the stack.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
