Which of the following should a developer use to ensure a block of code executes a defined number of times?

A 'for loop' is specifically designed for iterating a block of code a fixed number of times, typically by initializing a counter, defining a condition for the loop to continue, and specifying an increment or decrement step, making it ideal when the number of repetitions is known in advance.

A 'while loop' executes a block of code repeatedly as long as a specified condition remains true, which is generally used when the number of iterations is not known beforehand.

An 'if...else statement' is a conditional construct that executes one block of code if a condition is true and another if it is false; it is not used for repetitive execution.

A 'switch statement' is used for multi-way branching, executing different code blocks based on the value of a single expression, rather than for iterating code a defined number of times.
