This is a prewritten function that is built into a programming language.

1. a. standard function
2. b. library function
3. c. custom function
4. d. cafeteria function

Program Description Answer

The prewritten function that is used to build into a programming language is a library function.

Hence, the correct answer is option “B”.

Explanation of Solution

Library Function:

• Many programming languages are come with a library functions which means the functions are already written for the languages. It is called library function.
• These functions are built into the programming languages and the programmer can call that functions whenever they want to access it.
• The library functions perform most of the tasks that the programmers normally want to perform so it makes easier for the programmer.

Explanation for incorrect options:

Standard Function:

The standard function is not a valid build-in function.

Hence, the option “A” is wrong.

Custom Function:

The custom function is not a valid build-in function.

Hence, the option “C” is wrong.

The cafeteria function is not a valid build-in function.

Cafeteria Function:

Hence, the option “D” is wrong.
