What is a loop control statement?

A loop control statement plays a pivotal role in determining how the loop operates by directing the flow of control within it. This means that it determines when the loop starts, when it continues to execute, and when it ultimately stops. For example, in many programming languages, loop control statements such as 'break' and 'continue' modify the standard flow of looping constructs. The 'break' statement can terminate the loop immediately, while 'continue' can skip the current iteration and proceed to the next one.

In contrast, defining the structure of a loop refers to establishing its syntax and the components required (such as the initialization, condition, and increment), which does not solely govern the flow. Performing calculations within a loop pertains to the operations conducted during each iteration but does not influence the loop's structure or flow control. Initializing variables is a preliminary step before the loop begins executing, rather than an aspect of controlling the loop during its execution. Therefore, the assertion that a loop control statement dictates the flow of control in a loop accurately encapsulates its purpose and functionality.
