Final answer:
A conditional loop is an indefinite loop that runs based on user actions or external conditions. It continues to execute until a particular condition is met, making it a key structure in programming.
Step-by-step explanation:
A conditional loop is an indefinite loop in which the number of executions is determined by user actions. This type of loop continues to execute until a specific condition is met, which is often based on user input or certain events that occur during program execution.
Loops that execute for an indefinite number of times until certain conditions are met are essential in programming as they allow for processes that need to wait for an external condition or user interaction before they proceed to the next step.
