Which type of loop executes a set of instructions repeatedly with specified conditions?

The most suitable answer is the for loop, as it is specifically designed to execute a set of instructions a predetermined number of times based on specified conditions. This type of loop is commonly used for iterating over ranges or working with collections where the number of iterations is known ahead of time.

A for loop typically defines an initialization step, a condition that is checked before each iteration, and an increment step that updates the loop variable. The clear structure allows programmers to easily manage the number of iterations and ensures that the loop will be executed just as many times as required.

While other loop types, like while loops and do-while loops, also execute instructions based on conditions, they are generally more flexible for scenarios where the number of iterations isn't predetermined. A while loop checks the condition before entering the loop, and a do-while loop checks it after executing the block once, making them more suited for different use cases. Nested loops allow looping within another loop, but they do not inherently specify a number of iterations on their own without additional logic.
