Sample text

Prior to writing code, programmers often use pseudocode, which is a hybrid of English (or other language) and programming code. Thinking in pseudocode allows you to focus on how to solve the problem rather than language details or syntax. However, to be useful, the pseudocode must be specific enough that it can be translated into a working program. Recipes are good everyday examples of algorithms. They can be written at different levels of detail, depending on the expertise or experience of the cook.

Use // when you intend to use integer division. You do not need to write any functions other than main(). py that guesses an integer chosen by the user between 1 and 100. After each guess, the user indicates if the guess was too high, too low, or correct. Your program should use as few guesses as possible. You do not need to write any functions other than main(). 12 to add these features: (a) Allow the user to play more than once. (b) Report the total number of guesses taken after each round. (c) Allow the user to specify the upper limit, instead of always using 100.

To some extent, you have to limit your thinking to what a program can do; otherwise, you may write pseudocode that cannot be translated into a program. Recognize patterns. For example, accumulation loops occur in many different contexts (as you will see). Patterns like it expand the vocabulary you can think in. Think top-down or bottom-up. Top-down design starts with large process steps and gradually breaks each one down until there is enough detail to implement it. Bottom-up works in reverse, beginning with relatively detailed tasks, and then putting those together until there is a complete solution.
