While Loop is Best Suited for Unknown Number of Iterations
While loop is the best choice when the number of iterations is unknown because it repeats a block of code as long as a specified condition is true. Here's why:
Flexibility in Condition Checking
- While loop allows you to check the condition at the beginning of each iteration. This means you can continue iterating as long as the condition remains true, making it ideal for situations where the number of iterations is uncertain.
Dynamic Termination
- Since the condition is checked before each iteration, the loop can dynamically terminate when the condition becomes false. This flexibility is crucial when the exact number of iterations is not predetermined.
Example Scenario
- For instance, if you are reading user input in a program and need to keep prompting the user until a specific input is received, a while loop would be the perfect choice. You can continue looping until the desired input is provided without knowing in advance how many times the loop will run.
In conclusion, while loop is the most suitable loop construct when the number of iterations is unknown due to its flexibility in condition checking and dynamic termination based on the condition. It allows for a more adaptable and efficient way to handle situations where the exact number of iterations is uncertain.

The while loop is best suited when the number of iterations is unknown. It continues to execute as long as the condition specified in the loop header remains true.
