An algorithm is a sequence of instructions to solve a well- formulated computational problem specified in terms of its input and output. Pseudocode What is pseudocode? Pseudocode is a simplified, half-English, half-code outline of a com- puter program. Why use it? • Because it can help.

The format below is recommended for expressing your solutions in our class.

Each of these constructs can be embedded inside any other construct. These constructs represent the logic, or flow of control in an algorithm. It has been proven that three basic constructs for flow of control are sufficient to implement any "proper" algorithm. WHILE is a loop repetition with a simple conditional test at its beginning. CASE is a multiway branch decision based on the value of an expression. If you are developing a program along with other coders, you may find that pseudocode helps make your intentions clear.

Remember that pseudocode is subjective and nonstandard.

Pseudocode

There is no set syntax that you absolutely must use for pseudocode, but it is a common professional courtesy to use standard pseudocode structures that other programmers can easily understand. If you are working with others on a project—whether they are your peers, junior programmers, or non-technical collaborators—it is important to use at least some standard structures so that everyone else can easily understand your intent.

If you are enrolled in a programming course at a university, a coding camp, or a company, you will likely be tested against a taught pseudocode "standard". This standard often varies between institutions and teachers. Focus on the main purpose of pseudocode. It can be easy to revert to writing in code once you hit your stride.

Remembering the purpose of your pseudocode—explaining what each line of the program should do—will keep you grounded while creating the pseudocode document.

Use a plain-text editor. It can be tempting to use a word processor e.

File history

Start by writing down the purpose of the process. Dedicating a line or two to explaining the purpose of your code will help set up the rest of the document, and it will also save you the task of explaining the program's function to each person to whom you show the pseudocode.

Each statement in your pseudocode should express just one action for the computer. In most cases, if the task list is properly drawn, then each task will correspond to one line of pseudocode.

Consider writing out your task list, then translating that list into pseudocode, then gradually developing that pseudocode into actual, computer-readable code. Use white space and indentation effectively.

Using white spaces between "blocks" of text will help keep different components of your pseudocode isolated, and indenting different pieces of each block will indicate that those pieces of pseudocode go under a less-indented section. For example, a section of pseudocode that discusses entering a number should all be in the same "block", while the next section e. Capitalize key commands if necessary. Depending on your pseudocode requirements or the environment in which you're publishing the pseudocode, you may need to capitalize commands that will remain in the actual code.

For example, if you use "if" and "then" commands in your pseudocode, you might want to change them to read "IF" and "THEN" e.

Write using simple terminology. Remember, you're writing about what the project will do , not summarizing the code itself. This is especially important if you're writing pseudocode to serve as a demonstration for a customer who doesn't know coding, or as a project for a beginner programmer. Keep your pseudocode in the proper order. While the language you use to modify your pseudocode should be simple, you still need to keep each piece of your pseudocode in the order in which it needs to be executed.

Leave nothing to the imagination. Everything that is happening in the process must be described completely. Pseudocode statements are close to simple English statements.

Pseudocode does not typically use variables, but instead describes what the program should do with close-to-real-world objects such as account numbers, names, or transaction amounts.

Even if there is no standard for pseudocode, it will be easier for other programmers to understand your steps if you use structures from existing sequential programming languages. Consider the following structures: Organize your pseudocode sections.

If you have large sections of pseudocode that define other pieces of pseudocode within the same block, you may want to use brackets or other identifiers to keep everything contained. Brackets—both standard e. You can use this same method when writing pseudocode to leave notes that don't fit into the coding text.

Double-check your pseudocode for readability and clarity. You should be able to answer the following questions by the end of the document: Would this pseudocode be understood by someone who isn't familiar with the process?

Is the pseudocode written in such a way that it will be easy to translated it into a computing language? Does the pseudocode describe the complete process without leaving anything out? Is every object name used in the pseudocode clearly understood by the target audience? If you find that a section of pseudocode needs elaboration or it doesn't explicitly outline a step that someone else might forget, go back and add the necessary information.

Open a plain-text editor. Define your program. While not strictly necessary, writing a one- or two-sentence line at the top of the document will make clear from the beginning the intent of the program: This program will request a greeting from the user.

If the greeting matches a specific response, the response will be delivered; if not, a rejection will be delivered. Write the opening sequence. Just give it a good shake before using. In general, an algorithm can be described as a procedure to solve a problem.

Define the problem: State the problem you are trying to solve in clear and concise terms. List the inputs information needed to solve the problem and the outputs what the algorithm will produce as a result 3. Describe the steps needed to convert or manipulate the inputs to produce the outputs. Start at a high level first, and keep refining the steps until they are effectively computable operations. Test the algorithm: choose data sets and verify that your algorithm works!

WHILE 2. May Communications of the ACM 9 5 : — I think this is a good idea, because it helps you keep track of the variables that you will need in the algorithm and can help you think through what data types are needed.In such a case, I is referred to as a counter.

It can be easy to revert to writing in code once you hit your stride.

In the event that the user incorrectly chooses a response, you can have an error message ready: The procedure must break up the problem solution into parts that the recipient party can understand and execute. A procedure is a sequence of instructions written in terms of which evoke a proper operation.
