In C++, what control structure is typically used to execute code repeatedly?

In C++, the primary control structure that facilitates the repeated execution of code is the loop. Loops, such as for, while, and do-while, enable a programmer to run a block of code multiple times until a specified condition evaluates to false. This is essential for tasks that require repetition, such as iterating through arrays, processing user input until a sentinel value is entered, or performing an operation a set number of times.

Each type of loop serves different scenarios: a for loop is often used when the number of iterations is known beforehand; a while loop is suitable when the number of iterations is not predetermined and depends on a condition; and a do-while loop ensures that the block of code runs at least once before checking the condition.

Other structures, such as condition statements (like if and else), handle branching logic and executing code based on certain conditions but do not inherently repeat execution. The switch case directs the flow of execution to different sections of code based on the value of a variable without establishing repetition. A function call invokes a separate piece of code that can be executed, but it doesn't create repetition on its own unless combined with loops.

Thus, the loop is the
