C/C++ Mathematical Programs

Mathematical Algorithms in programming are the specialized method to solve arithmetic problems such as finding roots, GCD, etc. Most of us are familiar with the conventional methods and concepts used to solve such problems but they may not be the best choice in programming, such as the best choice for finding GCD in programming is Euclidean Algorithm.

In this article, we will discuss different optimal solutions for solving some common mathematical problems in C/C++.
