Concept Check

0/5

What is the main purpose of a utility function library in software development?

Only handles user interface elements

Limits application functionality

Increases code complexity unnecessarily

Provides reusable functions for common tasks

In a utility library, how does memoization optimize functions?

Increases memory usage significantly

Executes functions multiple times

Slows down program execution

Caches results to avoid recomputation

Why might a utility library include string manipulation functions?

To manage database connections

For enhancing graphical interfaces

To simplify text processing operations

For hardware device interactions

What risk is associated with overusing utility functions in a project?

Potential for code bloat and dependency

Always improves code readability

Reduces the need for testing

Eliminates all errors automatically

How does a utility library promote code maintainability?

By centralizing common functionalities

Through duplicating code everywhere

By complicating function calls

Via random function placements
