These languages have a specific syntax that must be adhered to when writing program's source code. If b is false !b is true. Pseudo code, and thus the algorithm are imperfect in many natural things, so it is necessary to re-think and write pseudo code, and then algorithm. There are different guide and tutorials which lean more towards language-specific pseudocode, examples of such are Fortran style pseudo code, Pascal style pseudo code, C style pseudo code and Structured Basic style pseudo code. line: = EZ Pseudocode = (c) Dave Mulkey 2012. The author will also write some sections in plain english instead of an actual programming language if it would take too long to write out in code or is unimportant. The operator assists callers by answering the line and connecting the caller to the correct person or department. Pseudocode is not a programming language, it is a simple way of describing a set of instructions that does not have to use specific syntax. For example, if we want to ask a user for a number between 1 and 10, we don't know how many times the user may enter a larger number, so we keep asking "while the number is not between 1 and 10". It uses the structural conventions of a normal programming language, but is intended for human reading rather than machine reading. It's more efficient with the partially sorted array or list, and worst with the descending order array and list.
