This question is not complete and the completed question is given below:
Alexis has six different pieces of jewelry to show and describe on a web page. Two are gold, and the rest are silver. Based on the principles of proximity, how would she display these pieces on her page?
- She would separate each and provide some distance between
- them
- She would mix the pieces and keep them all close together
- She would make two columns of jewelry with an equal number of pieces in each
- She would group the gold together, and the silver together
Based on the principle of proximity, the correct answer to this question is:
She would group the gold together, and the silver together.
As you know that the principle of proximity states that things that are close together appear to be more related than things that are spaced farther apart. So based on this principle she needs to make two groups gold and silver. So, based on the proximity principle, she would group the gold together, and the silver together.
Answer:
An operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.
Technologies that allow for instant worldwide communication include mobile phones and internet access. Cell phones
, wireless devices and smart phones are technologies that have made global communication instant and more effective.
The internet and the development of digital technology (computer-based technology) in particular, have made the most significant impact on globalization.

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();
