What does the term "iteration" refer to in programming?

• A. The process of defining variables in code
• B. The repetition of a process or set of instructions, often through loops
• C. A method of error-checking
• D. A form of object-oriented programming

Answer: (B)

The term "iteration" in programming specifically refers to the repetition of a process or set of instructions, often through loops. This concept is fundamental in programming as it allows developers to execute a sequence of code multiple times, enabling them to efficiently process data collections, perform calculations repeatedly, or continually check conditions. For example, in a loop construct such as a "for loop" or a "while loop," iteration allows the program to run a block of code as long as a specified condition holds true. This is particularly useful when working with arrays or lists where operations need to be performed on each element. Understanding iteration is key to writing effective algorithms and can significantly enhance the capabilities and efficiency of a program by automating repetitive tasks. The other choices do not accurately capture this core concept of iteration in programming.
