Answer:
Give at least one reason why it's useful to learn how to solve and program solutions with a limited set of commands. So that when there is more commands we know how to use the ones we have. parameters help generalize the solution to a specific problem. how are functions with parameters an example of abstraction?
Answer:
False.
Explanation:
When we declare a variable as reference type we have to initialize that variable otherwise the compiler will give error that the reference variable is not initialized.You also cannot initialize the variable Foo& with NULL value because it is a reference variable and we have to initialize it.
On the other there is no need to initialize the variable Foo * since it is a pointer it can also store NULL value.
So the answer is only Foo* can store NULL value not Foo &.

Answer:
The correct answer to the following question is option A). Install a HIPS on the web servers
Explanation:
HIPS stands for Host-Based Intrusion Prevention System or Host Prevention System.
HIPS is the program or system which protects your computer system against virus and the other malware and it also protects from unknown and known malicious attacks.
