What is a condition-controlled loop in Python?

What is a condition-controlled loop in Python?

CONCEPT: A condition-controlled loop causes a statement or set of statements to repeat as long as a condition is true. In Python you use the while statement to write a condition-controlled loop. The while loop gets its name from the way it works: while a condition is true, do some task.

What are condition-controlled iteration in computer science?

Condition-controlled iteration repeatedly executes a section of code until a condition is met – or no longer met.

Is while loop condition-controlled loop?

Condition-controlled loops are also called WHILE loops or WHILE-ENDWHILE statements. Whether the condition is met or not is checked at the beginning of the loop. If the condition is ‘true’ it repeats, if not then the code is not executed.

What is a count-controlled loop explain with an example?

A count-controlled loop is used when the number of iterations to occur is already known. In this example, the variable ‘count’ is used to keep track of how many times the algorithm has iterated. This variable controls the loop. The algorithm will continue to iterate until the value of count has reached 5.

When would you use a controlled control loop?

Condition-controlled loops have a condition that is tested at the start of the iteration to determine whether or not the iteration should occur. With each iteration, the condition is tested again. As long as the condition is being met (ie is true), the iteration continues.

What is sentinel controlled loop?

A sentinel controlled loop is also called an indefinite repetition loop because the number of iterations is not known before the loop starts executing. An example of a sentinel controlled loop is the processing of data from a text file of unknown size.

What is a loop iteration?

A loop is defined as a segment of code that executes multiple times. Iteration refers to the process in which the code segment is executed once. One iteration refers to 1-time execution of a loop. A loop can undergo many iterations.

Which type of iteration in Python is known as a count-controlled loop?

The for loop as a Count-Controlled loop iterates a specific number of times. In the for clause, variable is the name of a variable. Inside the brackets is a sequence of values, that is comma separated. (in Python this is called a list).

What is the difference between condition-controlled and count controlled loops?

1. it uses a counter to keep track of how many times the algorithm has iterated. 2. A condition-controlled loop is so called because iteration continues while, or until, a condition is met.

Which of the following is a count controlled loop?

A do…. while loop is an example of sentinel controlled loop. A while loop is an example of counter controlled loop.

What is the difference between a condition-controlled loop and count-controlled loop?

4 Answers. Don’t overthink this: for loop if you have something that has to be done for a exact number of times, while loop if you want something done while a condition is true. “Counter controlled” means that you know exactly the number of times the loop has to be executed.

What happens if a condition of a loop is always true?

The condition is tested at the beginning of each iteration of the loop. If the condition is true ( non-zero ), then the body of the loop is executed next. If the condition is false ( zero ), then the body is not executed, and execution continues with the code following the loop.

What does a condition-controlled loop mean in programming?

In computer programming, conditional loops or repetitive control structures are a way for computer programs to repeat one or more various steps depending on conditions set either by the programmer initially or real-time by the actual program.

Do loop with condition?

You can use Do…Loop statements to run a block of statements an indefinite number of times. The statements are repeated either while a condition is True or until a condition becomes True. Repeating statements while a condition is True. There are two ways to use the While keyword to check a condition in a Do…Loop statement. You can check the condition before you enter the loop, or you can check it after the loop has run at least once.

What is an infinite for a loop in C?

Infinite Loop in C What is infinite loop? An infinite loop is a looping construct that does not terminate the loop and executes the loop forever. It is also called an indefinite loop or an endless loop.

What is a conditional loop?

In computer programming, conditional loops or repetitive control structures are a way for computer programs to repeat one or more various steps depending on conditions set either by the programmer initially or real-time by the actual program. A conditional loop has the potential to become an infinite loop…
