3.23 Problem Solving Using Abstraction

3.23 Problem Solving Using Abstraction

Abstraction involves focusing on the essential features of a problem while ignoring

unnecessary details. This technique helps manage complexity. Examples of abstraction

in computing:

ˆ ata types D
ˆ unctions F

ˆ lasses C
ˆ nterfaces I

Example: Abstraction Using Functions

The user does not need to know how the function works internally—only what it does.

3.24 Problem Solving and Debugging

Debugging is a systematic problem-solving activity that involves:

ˆ dentifying errors I

ˆ nalyzing causes A

ˆ esting hypotheses T
ˆ erifying fixes V

Effective debugging requires patience, logic, and critical thinking.

Debugging Example:
