Computer programming and programming languages have gained much traction in the recent decade. Advancements in software development and hardware improvements have made computer programming advancements possible. 

This has garnered the attention of several youngsters who want to have a piece of the pie, so to speak. 

Programming languages, especially C, have been very popular. C programming is a computer programming language used to develop applications and software.

There are, however, certain basic things that you must understand to have mastery over the programming language. Series in C programming is one among them.

Series in C programming is a must-have tool in a programmer's arsenal. Learning this concept is necessary whether you are a newbie or a veteran. A series is an object or an event of a similar kind that comes after one another.

In this blog, we will learn the basics of the series in C programming. We will also delve into the importance and utility of the series.

We will also be learning about using the Fibonacci series in C++. Furthermore, we will shed some light on the role of the [array in C++](https://www.codingninjas.com/studio/library/array-in-cpp) in optimizing memory management.

Let us now delve into C programming and learn all about the series and their utilization in creating software and applications.

What is Series in C programming?

Series in C programming is the sequence of elements that follow a specific pattern. Series in C programming is often used in mathematical equations and calculations by programmers in their algorithms. Understanding and then utilizing these series patterns is paramount for combating many problems.

The series in c programming can be either descending or ascending. Every element that comes after the other is obtained by doing mathematical calculations like adding, subtracting, multiplying or dividing the previous element by a specific element. This process is repeated multiple times. 

C programmers use loops and conditional statements for and while to get the decreasing and increasing sequences with set patterns. 
Moreover, series in C programming can be of various forms, all with their unique process and utilities. The most common among them are:

Arithmetic Series

The arithmetic series in C programming is one of the most common series. Each element or number in this series comes from adding a common difference to the previous number or element. 

Loops are typically used in C programming by adding the value of each element to create an arithmetic series.

This is basically like the arithmetic progression in high school mathematics we were taught. Typically the arithmetic series in C programming takes the form of  

a, a + b, a + 2b, a + 3b, ..., 

The 'a' here indicates the original number or the initial term. The ‘b’ is for the common difference added to the numbers. The 3 dots (ellipses) indicate that this arithmetic series can go on for infinity. 

Let us clear it up with an example.

Let’s take an arithmetic series where the initial number is 2, and the common difference to be added is 4. Using the form mentioned above, the arithmetic series would look like this:

 2, 6, 10, 14, ...

Geometric Series

Each element in a geometric series comes from multiplying the initial number or element by a common ratio. This keeps on repeating multiple times to create a Geometric series. Loops that multiply each number or element by the common ratio create the Geometric Progression.

If you remember your high school math lessons, this series is like the geometric progression we were taught. Typically the geometric series in C programming takes the form of 

a, a * r, a * r^2, a * r^3, ..., 

The 'a' here indicates the original number or the initial term. The 'r' is for the common ratio multiplied by the numbers. The 3 dots (ellipses) indicate that this geometric series can go on for infinity.

Let us take an example. A geometric series with the initial number 3 and common ratio 2 multiplied. The Geometric series would look like this,

 3, 6, 12, 24 ...

Now let’s talk about another common type of the series in detail, the Fibonacci Series in C++.

Fibonacci Series in C++ 

Fibonacci series in C++ refers to a number sequence where every number, except for the first two, is the sum of the two numbers before it. The Fibonacci series starts with 0 and 1 as the first two numbers. 

Typically, the Fibonacci series is defined as:

F(0) = 0
F(1) = 1
F(n) = F(n-1) + F(n-2) for n > 1

If we follow this pattern, the Fibonacci series in C++ starts as 0,1,1,2,3,5,8,13,...

The Fibonacci series in C++ can be generated by 2 approaches.
Iterative Approach
In this approach, a loop is used to calculate the Fibonacci series. It works by updating the values of the current number and the previous numbers' values in each repetition. 
Recursive Approach
In this approach, we declare a function Fibonacci which will calculate the Fibonacci numbers in the series until we get the desired series.
Now let’s move on to the next part of this blog, i.e., array in C++.
What is Array in C++?
Arrays in C++ are an important tool to have in your programming arsenal. By definition, arrays in C++ are a collection of data types identical in value, such as char, int, double, float, etc. 
These are stored using the index value and can be retrieved just by using the index value. Furthermore, it gathers all variable occurrences into a single variable.
In simple terms, think of an array in C++ like a Tupperware container. In this container, you can store multiple things of the same kind. Each thing has its place in the container, and you. can easily find it using the assigned number given to that particular item.
Conclusion
In summary, series in C programming refers to a sequence of elements or numbers that follow a specific mathematical pattern. These can be of several types, such as the [Fibonacci series in C++](https://www.codingninjas.com/studio/library/various-programs-for-fibonacci-numbers-in-c).
Furthermore, arrays in C++ are important in gathering similar data types and can be retrieved using the index value.
Understanding these concepts in C programming helps programmers develop solid algorithmic solutions for various computational tasks.
