Can we write for loop in while loop?
All for loops can be written as while loops, and vice-versa. In general, you should use a for loop when you know how many times the loop should run. If you want the loop to break based on a condition other than the number of times it runs, you should use a while loop.
How do you repeat a program while loop?
repeat… while Loop
- The body of the loop is executed at first. Then condition is evaluated.
- If condition evaluates to true , the body of the loop inside the repeat statement is executed again.
- condition is evaluated once again.
- This process continues until condition evaluates to false . Then the loop stops.
What is the formula for while loop?
Syntax. do { statement(s); } while( condition ); Notice that the conditional expression appears at the end of the loop, so the statement(s) in the loop executes once before the condition is tested. If the condition is true, the flow of control jumps back up to do, and the statement(s) in the loop executes again.
When to use a loop in a program?
Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. For example, if we want to ask a user for a number between 1 and 10, we don’t know how many times the user may enter a larger number, so we keep asking “while the number is not between 1 and 10”.
Which is the n th iteration of a for loop?
When that test is true, that particular loop cycle is the n th iteration. That way we can execute special code during those loop cycles. This does require that our loop has a variable that counts its loop cycles. This is something the for loop does by default.
How often should a C # loop execute the same code?
Usually a C# loop executes the same code with each loop cycle. That way we can process an array or work through a file. But sometimes we need to do something different every n th loop cycle. We for example need to calculate the average every 5 values, or write data to a file every 20th loop cycle.
When to use continue statement in for loop?
Continue statement can be used in for loop when you want to fetch a specific value from the list. In our example, we have declared value 10-20, but between these numbers we only want those number that are NOT divisible by 5 or in other words which don’t give zero when divided by 5.
