The COBOL perform loop is the equivalent of which of the following structures found in other languages, such as Java or C++

  1. For loop

  2. Do-While loop

  3. Method

  4. None of the Above


Correct Option: B

AI Explanation

To answer this question, you need to understand the COBOL perform loop and its equivalent structure in other programming languages.

The COBOL perform loop is used to repeat a set of statements a certain number of times or until a condition is met. It is similar to the do-while loop found in other languages such as Java or C++.

Let's go through each option to understand why it is correct or incorrect:

Option A) For loop - The for loop is used to iterate a specific number of times. It has a defined initialization, condition, and increment/decrement, which is different from the COBOL perform loop. Therefore, option A is incorrect.

Option B) Do-While loop - The do-while loop is used to repeat a set of statements until a certain condition becomes false. This is the equivalent structure to the COBOL perform loop, as both allow for repeating a set of statements until a condition is met. Therefore, option B is correct.

Option C) Method - A method is a subprogram or a function that performs a specific task. It is not directly equivalent to the COBOL perform loop. Therefore, option C is incorrect.

Option D) None of the Above - Since the correct answer is option B, which states that the COBOL perform loop is equivalent to the do-while loop, option D is incorrect.

The correct answer is B) Do-While loop. This option is correct because the do-while loop is the equivalent structure to the COBOL perform loop, as both allow for repeating a set of statements until a condition is met.
