What does the while loop do in the provided C++ code?

Executes a statement as long as the condition is true
Executes a statement once before checking a condition
Executes a block of code a fixed number of times
Compares two values and executes a block of code if they are not equal

The correct answer is: Executes a statement as long as the condition is true

A while loop executes a statement repeatedly as long as a given condition is true. This is useful for iterating through data or performing a task multiple times. Option B, executing a statement once before checking a condition, describes a do-while loop. Option C incorrectly describes a for loop, which executes a block of code for a fixed number of times. Option D describes an if statement, which only executes a block of code if a specified condition is true.
