When to use a while or for loop?

When to use a while or for loop?

When the number of times is not known before hand, we use a “While” loop. The For Loop The for loop is used to repeat a section of code known number of times.

Which is an example of a for loop?

The for loop is used to repeat a section of code known number of times. Sometimes it is the computer that knows how many times, not you, but it is still known. Some examples: Unknown number of times: “Ask the User to Guess a pre-determined number between 1 and 100”.

Which is the first iteration of the Python for loop?

Iteration 1: In the first iteration, 0 is assigned to x and print (“python is easy”) statement is executed. Iteration 2: In the second iteration, 1 is assigned to x and print (“python is easy”) statement is executed. Iteration 3: In the third iteration, 2 is assigned to x and print (“python is easy”) statement is executed.

When to break out of the loop in C #?

At any point within the body of an iteration statement, you can break out of the loop by using the break statement, or step to the next iteration in the loop by using the continue statement. The for statement executes a statement or a block of statements while a specified Boolean expression evaluates to true.

Is there a shorter / simpler version of the for loop to?

It’s convenient and short (shorter than any of the other answers) and will run exactly i times (because postfix decrement returns value before decrementation). Thanks for contributing an answer to Stack Overflow!

The For Loop. The for loop is used to repeat a section of code known number of times. Sometimes it is the computer that knows how many times, not you, but it is still known.

Which is the design pattern for a for loop?

The design pattern for a for loop is: Matlab for index = start_value : increment_value : end_value % Do this code end % implied increment by 1 for index = start_value : end_value % Do this code end C, Java
