Unit4-04: Break Statement

Learning Outcome

At the end of this lesson, you will be able to:

understand and use a break statement inside a loop

Quiz Questions

With a pencil and paper, answer the following questions:

What is the minimum number of times a FOR loop will execute? Why?
Which other loop is a FOR loop most similar to? Why?
Write the code for a for loop in Python that does the following:
- Display all the even numbers, one per line, from -20 to 40.
What is displayed to the console by the following code:

Review

for loops
- in Python:
  - for counter in range (user_num + 1):
    OR
    for counter in range(-5, user_num + 1):
    OR
    for counter in range(2, user_num + 1, 3):
- in C++:
  - for (counter initialization; boolean expression; counter increment/decrement) {
    ...
    }

Lesson

from the online book Computer Based Problem Solving by Patrick Coxall, read:
- Break Statements
  - used to break out of a loop when a boolean condition is triggered

Flowchart for Break Statement

Here is the Problem:

Write a program that generates a random correct guess between 0 and 9.
It then uses a while TRUE loop to keep asking the user to guess the number until they guess correctly.
It uses a break statement to exit the loop once they guess the correct number.
Make sure your program does not crash if a user enters invalid input!
