College Board 3.14 Libraries

A software library contains procedures that may be used in creating new programs.
Existing code segments can come from internal or external sources, such as libraries or previously written code.
The use of libraries simplifies the task of creating complex programs.
Application program interfaces (APIs) are specifications for how the procedures in a library behave and can be used.
Documentation for an API/library is necessary in understanding the behaviors provided by the API/library and how to use them.
A file that contains procedures that can be used in a program is considered a library.
An Application Program Interface (API) provides specifications for how procedures in a library behave and can be used.
Many large tech companies and social media companies provide APIs for programmers to interact with their products.

The exam reference sheet provides Text: RANDOM(a, b) Block: RANDOM a, b

which generates and returns a random integer from a to b, inclusive.
Each result is equally likely to occur. For example, RANDOM(1, 3) could return 1, 2, or 3.
Using random number generation in a program means each execution may produce a different result.
We can use the results from randomization to program simulations.

RANDOM a, b generates a number from a to b inclusive.
Each result from the randomization is equally likely to occur.
Using random number generation in a program means each execution may produce a different result.
We can use the results from randomization to program simulations.
