What Is an Algorithm?
💎Algorithm: an effective method expressed as a finite list of well-defined instructions for solving a
problem.
💎An algorithm is the list of instructions and rules that a computer needs to do to complete a task.
💎In essence, algorithms are simply a series of instructions that are followed, step by step, to do something useful or solve a problem.

Design can be shown using algorithms.
An algorithm must possess the following properties:
💎finiteness: The algorithm must always terminate after a finite number of steps.
💎definiteness: Each step must be precisely defined; the actions to be carried out must be rigorously and
unambiguously specified for each case.
💎input: An algorithm has zero or more inputs, taken from a specified set of objects.
💎output: An algorithm has one or more outputs, which have a specified relation to the inputs.
💎effectiveness: All operations to be performed must be sufficiently basic that they can be done exactly
and in finite length.

1. Flowchart
💎Is a picture (graphical representation) of the problem
and solving process.
💎A flowchart gives a step-by-step procedure for solution of a problem

2. Pseudo-code
💎fake and Informal language that helps programmers to plan an algorithm.
💎It is somewhat similar to everyday English with a feel of programming language.

What is C++?
📌 C++ is a cross-platform language that can be used to create high-performance applications.
📌 C++ was developed by Bjarne Stroustrup, as an extension to the C language.
📌 C++ gives programmers a high level of control over system resources and memory.
