Pseudocode is commonly used in textbooks and scientific publications related to computer science and numerical computation to describe algorithms in a way that is accessible to programmers regardless of their familiarity with specific programming languages.
The following pseudocode guarantees synchronization between barber and customer and is deadlock free, but may lead to starvation of a customer. The problem of starvation can be solved with a first-in first-out (FIFO) queue. The semaphore would provide two functions: wait() and signal(), which in terms of C code would correspond to P() and V ...

In computer programming, the act of swapping two variables refers to mutually exchanging the values of the variables. Usually, this is done with the data in memory. For example, in a program, two variables may be defined thus (in pseudocode): data_item x := 1 data_item y := 0 swap (x, y);
The use of pseudocode is completely language agnostic, and is more NPOV with respect to programming languages in general. Pseudocode also provides far more flexibility with regard to the level of implementation detail, allowing algorithms to be presented at however high a level is required to focus on the algorithm and its core ideas, rather ...
Pseudocode is similar to skeleton programming, however deviates in the fact that pseudocode is primarily an informal method of programming. [3] Dummy code is also very similar to this, where code is used simply as a placeholder, or to signify the intended existence of a method in a class or interface.
The if–then or if–then–else construction is used in many programming languages. Although the syntax varies from language to language, the basic structure (in pseudocode form) looks like this: If (Boolean condition) Then (consequent) Else (alternative) End If. For example: If stock=0 Then message= order new stock Else message= there is ...
For example, given b = 5, e = 3 and m = 13, dividing 5 3 = 125 by 13 leaves a remainder of c = 8. Modular exponentiation can be performed with a negative exponent e by finding the modular multiplicative inverse d of b modulo m using the extended Euclidean algorithm .
