What is the job of the counter in the while loop?
The first line of the while loop creates the variable count and sets its value to 1. The second line checks if the value of the count is less than 11, and if so, executes the body of the loop. The loop body prints the current value of counter and then increments the value of counter.

What are the three steps to writing a while loop?
4.1. 1. Three steps to write a loop
- Initialize the loop variable (before the while loop)
- Test the loop variable (in the loop header)
- Change the loop variable (in the body of the while loop at the end)
What is the purpose of the Do While loop?
In most computer programming languages, a do while loop is a control flow statement that executes a block of code at least once and then repeatedly executes the block or stops executing it, based on a given Boolean condition at the end. of the block. .
How do you start writing a while loop?
while loop example
- step 1: The count variable is initialized to the value 1 and then tested for the condition.
- step 2: if the condition returns true, then the statements inside the body of the while loop are executed; otherwise, control exits the loop.
How is a while loop used in programming?
The above program uses a while loop, which is used to execute a set of programming statements enclosed within {….}. Here, the computer first checks whether the given condition i.e. the variable “a” is less than 5 or not and if it finds the condition is true, then it enters the loop body to execute the given statements.

Where does the DO WHILE loop check the condition?
If you remember how for and while loops work, you’ll remember that these types of loops test the loop condition at the beginning of the loop. Unless the condition is met, the loop will not execute. The do while loop tests the condition at the end of the loop.
What is the purpose of a loop statement?
To conclude, a loop statement allows us to execute a statement or group of statements multiple times. Below is the general form of a loop statement in most programming languages:
