Also, the variable names should be replaced with a better description of what they will eventually contain, rather than the variable names themselves. Computers need a very strict input syntax to run a program, but humans (especially non-programmers) may find it easier to understand a more fluid, subjective language that clearly states the purpose of each line of code. Is the pseudocode written in such a way that it will be easy to translate it into a computing language? They are as follows: FizzBuzz is a standard coding and interview problem in which we must write a code to print Fizz, Buzz, and FizzBuzz when the multiple of 3 and 5 occurs. It keeps the body of every component isolated, and indenting different pieces of each block will indicate that those pieces of pseudocode go under a less intended section. You might even want to get rid of any coding commands altogether and just define each line's process in plain language. What is the purpose? Also works as a rough documentation, so the program of one developer can be understood easily when a pseudo code is written out. . Describing how an algorithm should work.
