What is the main purpose of a 'while' loop in programming?
What is the main purpose of a 'while' loop in programming?
- To initialize loop variables
- To create a loop that repeats for a fixed number of iterations
- To execute a block of code as long as a certain condition is true (correct)
- To skip the loop entirely if the condition is not met
What happens if the condition in a 'while' loop is never false?
What happens if the condition in a 'while' loop is never false?
- The loop will not execute at all
- The code inside the loop will be skipped
- The loop will execute forever in a loop known as an infinite loop (correct)
- The loop will execute once and then terminate
What is one of the essential steps for implementing a count-controlled loop?
What is one of the essential steps for implementing a count-controlled loop?
- Changing the loop type to 'for' loop instead of 'while' loop
- Initializing the loop variable (correct)
- Using multiple conditions within the loop
- Testing the loop variable to determine if the condition is true
