How to Write an Algorithm?
There are no well-defined standards or rules for writing algorithms. Rather, it is problem and resource dependent. Algorithms are never written to support a particular programming code. As we know that all programming languages share basic code constructs like loops (do, for, while), flow-control (if-else), etc. These common constructs can be used to write an algorithm.
Let’s try to learn algorithm-writing by using an example.
Problem – Write an algorithm to multiply two numbers and display the result.
step 1 – START
step 2 – declare three integers a, b & c
step 3 – define values of a & b
step 4 – multiply values of a & b
step 5 – store output of step 4 to c
step 6 – print c
step 7 – STOP
We design an algorithm to get a solution of a given problem. There can be more than one solution to solve the given problem.
