Answer:
cin.ignore function written as cin.ignore()
Explanation:
- As we know that cin is an object that is used to obtain the input entered by the user through the keyboard.
- cin.ignore() is a function which is used to ignore or skip one or more characters in the keyboard buffer.
- Keyboard buffer is a small storage area which is used to store keystrokes.
- When a key is pressed on the keyboard it is referred to as a keystroke.
- So before processing, these keystrokes are stored in keyboard buffer.
- So when we use cin to input a character from the user through the keyboard, the keyboard buffer must be empty. If that's not done then the character entered will be taken by the buffer of previous variable.
- Lets take an example of why we want to use cin.ignore() function.
- For example you want the employee (user) to enter his name and you are using cin to read this name from the user.
char empname[8];
cin>>empname;
- Now if the user types his name lets say Anonymous and press enter key this will be taken as new line character and it will store this newline character \n into the buffer.
- cin >> statement reads data from the buffer and stops reading when it reaches newline character.
- So Anonymous is read in and stored in empname variable but newline character is left in the keyboard buffer.
- Lets say after cin>>empname we write another statement that takes a character from user. A user wants to enter character "a".
char character;
character = cin.get();
- When cin.get finds the newline character \n in keyboard buffer, it uses it (as cin.get can read the newline character in the buffer) without waiting for the user to input "a".
- So cin.ignore() function is used to avoid such situation.
- We can specify the characters to be ignore within the cin.ignore() function such as cin.ignore(10,'\n') will ignore 10 characters in the buffer before taking new line or until a \n character comes.
- You can simply use cin.ignore() which will ignore the very next character just as \n in our example. In our example we can use cin.ignore() after the cin>>empname; and before using cin.get();
It would be A because B could be answered best with a poll graph, C with a pie graph, and D with a bar graph. Line graphs typically show speed and rate so A makes the most sense, but you are still able to do the other questions on a line graph.
Main points are key ideas that support a thesis and helps an audience understand and remember what is most important about a speaker's topic, while sub points are supporting points like <span><span>examples, definitions, testimony, and statistics that support or illustrate a speaker's main points.

Answer:
The countermeasure is basically recommended against the attackers for defending various routing attacks. Routing is one of the most generally assaulted segments in a system and a lot of system the executives work centers around checking conduct of switches.
The single router has more than one unit for bundle handling. This encourages quicker handling. This preparing unit is finished programming which can be undermined by an aggressor.
So an additional free equipment is implanted into the switch which can do observing to recognize the product assaults. Maintain a strategic distance from over composition the addresses.
Be movement at time when all of a sudden if anything incorrectly happens we should be in a situation to deal with and deal with the issue since it causes more harm when time runs.
