pseudocode examples

Previously, I thought that the role of pseudo code is only to make the logic of the program clearer, and I can only show it to myself. Today I saw the code complete with a very deep experience. The first is that pseudocode is not only used for writing code, but can be directly used as a program comment. Let's look at an example to see how to write a good pseudocode and use it. Increment resource number by 1

That is to say, even if the number of dictionary elements increases, efficiency will not be affected.3. pseudocode Pseudocode is used to des

Coding is to solve a certain problem (whether it is a question on OJ or a project). Before solving the problem, we should fully analyze the problem (mining the implied conditions of the question, analysis of project requirements), coding becomes a matter of course only after you fully understand the problem and have a clear idea. In the past, when I was doing a question on OJ, I used to write code when I saw the question and never analyzed the various conditions of the question. This is wrong.★W

Pseudocode and Flowchart I. Syntax Rules of pseudocode(1) In pseudocode, each command occupies one line; (2) The command is not followed by any symbol (the statement in C should end with a semicolon );(3) The "indent" in the writing indicates the branch program structure in the program. The statements of the level-1 module are indented to those of its parent modu

structure in the program. This indent style also applies to if-then-else statements. Replacing the begin and end statements in traditional Pascal with indentation to represent the block structure of the program can greatly improve the clarity of the Code. The statements in the same module have the same indentation, the statements of the level-1 module are indented to those of its parent module. For example: line 1 line 2 sub line 1 sub line 2 sub line 1 sub line 2 sub line 3 in Pascal, this rel

5 typical php curl examples and phpcurl classic examples I use php and curl mainly captures data. Of course we can use other methods to capture data, such as fsockopen and file_get_contents. However, you can only capture those pages that can be accessed directly. It is more difficult to capture pages with page access control, or to log on to pages after logon. 1. capture files without Access Control 2. Use
