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.
A simple pseudocode implementation of the smoker who has the supply of tobacco might look like the following: def tobacco_smoker (): repeat : paper . wait () matches . wait () smoke () tobacco_smoker_done . signal ()
PSeInt is designed to assist students who start in the construction of computer algorithms or programs. The pseudocode is usually used as the first contact to introduce basic concepts such as the use of control structures, expressions, variables, etc., without having to deal with the particularities of the syntax of a real language.
An example of brace notation using pseudocode which would extract the 82nd character from the string is: a_byte = a_string{82} The equivalent of this using a hypothetical function 'MID' is:
On the right Nicomachus's example with numbers 49 and 21 resulting in their GCD of 7 (derived from Heath 1908:300). In mathematics , the Euclidean algorithm , [ note 1 ] or Euclid's algorithm , is an efficient method for computing the greatest common divisor (GCD) of two integers , the largest number that divides them both without a remainder .
A simple example will now be presented to show how a thread could be excessively delayed due to a lack of fairness in lock acquisition. Assume a case where three threads, each executing on one of three processors, are executing the following pseudocode that uses a lock with no consideration for fairness.
A compiler may produce pseudo code that is then translated to machine code by a pseudo code definition in the target matchine code instruction. Pseudo code used in this way is an abstraction allowing the translation of a high level language to an intermediate pseudo code instruction set that can then be defined for a specific target: processor.
Long division is the standard algorithm used for pen-and-paper division of multi-digit numbers expressed in decimal notation. It shifts gradually from the left to the right end of the dividend, subtracting the largest possible multiple of the divisor (at the digit level) at each stage; the multiples then become the digits of the quotient, and the final difference is then the remainder.
