A(n) _____ specifically executes some block of code repeatedly as long as a given condition is true.

Question

BlackTom AI · Accepted Answer

The question asks about a construct that repeatedly executes a block of code as long as a given condition remains true.
Option 1: logical OR — This is a boolean operator used to combine two conditions and does not by itself control repeated execution. It does not specify looping behavior.
Option 2: zero-index — This term pertains to numbering elements starting at zero and has no relation to executing code blocks or looping constructs.
Option 3: while loop — This is the standard looping construct in many programming languages that continues to run the enclosed block while the specified condition evaluates to true. It directly matches the description of repeatedly executing code under a condition.
Option 4: access modifier — This concept controls visibility and access to classes, methods, or fields, not the repetitive execution of code blocks.
