Final answer:
A repeating section of the code that continues until a counter reaches its limit is called a loop, with the 'for' loop being a common example. Loops are essential in programming for running a series of statements multiple times.
Step-by-step explanation:
A repeating section of code that repeats until a counter reaches its limit is known as a loop. In programming, loops are fundamental concepts that execute a sequence of statements multiple times. They continue to process until the predefined condition, often involving a counter that increments with each iteration, is met. A common example of a loop is the for loop, which runs a set number of times, determined by the counter's limit. Loops are utilized in various programming languages like Python, Java, C++, and many more to perform tasks such as iterating over arrays, repeating computations, or processing user input.
