Which of the following best describes the purpose of debugging programs?

A.
To generate random data that can be used to test programs before implementing them

B.
To ensure that program coding flaws are detected and corrected.

C.
To protect, during the programming phase, valid changes from being overwritten by other
changes.

D.
To compare source code versions before transferring to the test environment.

Explanation:
A bug is a coding error in a computer program. The process of finding bugs before
program final users is called debugging. Debugging starts after the code is first written and
continues in successive stage as code is combined with other units of programming to form a
software product, such as an operating system or application. The main reason to debug is to
detect and correct errors in the program.
