Which term describes breaking down complex problems into smaller, easier to solve parts?

• A. Decomposition
• B. Flowchart
• C. Sequence
• D. Selection

Answer: (A)

Decomposition is the process of breaking a complex problem into smaller, more manageable parts. By dividing the task, you can design, test, and understand each piece separately, making the overall solution easier to develop and debug. In programming, this often means creating functions or modules for each subtask and then combining them to solve the whole problem. A flowchart shows the steps of a process visually, but it’s a diagram tool rather than the act of breaking the problem down. Sequence refers to the order in which steps are carried out, and selection deals with making choices based on conditions. So, the best term for breaking down a problem into easier-to-solve parts is decomposition.
