A developer needs to create a program that will process a list of customer names one by one, performing the same set of operations on each name until the entire list has been processed. Which programming construct is best suited for this task?
- ALooping construct
- BVariable declaration
- CBranching statement
- DFunction definition
Show answer & explanationAnswer & explanation
Correct answer: A. Looping construct
A looping construct is specifically designed to repeatedly execute a block of code for a specified number of times or until a certain condition is met, making it ideal for iterating through a list.
Why the other options are wrong
- B. Variable declarations reserve memory for data and do not involve code execution or repetition.
- C. Branching statements execute code conditionally, not repeatedly.
- D. Function definitions create reusable blocks of code but do not inherently handle repetition over a list.
Looping Construct
A programming construct that repeatedly executes a block of code until a specified condition is met or for a fixed number of iterations.
- Automates repetitive tasks.
- Common types include 'for' loops and 'while' loops.
- Essential for processing collections of data.
Memory trick: Repeat tasks with loops, like a record on repeat.
