A. true b. false: a vector object automatically expands in size to accommodate the items stored in it.

Answer : True  

Explanation: Vectors can hold, data of the same type and can automatically expand accordingly and change it’s size. The date stored in vectors should be linear.  

-The syntax for vector is vector<int>v;

-Mostly this is used in C++ as an alternative to arrays  

-If you want to use vector in your program then define it in the header first  i.e.

#include <vector>

-Push back is a function, that is used to insert an element into the vector  

-Pop back removes the element from the vector  

the answer is d underlined.

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.
