### What is Fibonacci Sequence

#### Explain Fibonacci Series

#### What are Fibonacci Numbers

This program with title “Fibonacci Program in C Programming” is based on a special series in mathematics. The Fibonacci sequence is a series of numbers starting from first two numbers 0 and 1 by definition. Then every other number is the sum of previous two numbers. 0,1,1,2,3,5,8,13 … and so on.

### How Fibonacci sequence explained

The popular Wikipedia says about Fibonacci Sequence : In mathematics, the **Fibonacci numbers**, commonly denoted *F _{n}* form a sequence, called the

**Fibonacci sequence**, such that each number is the sum of the two preceding ones, starting from 0 and 1. That is

## Why This Series is Called Fibonacci?

About the Man Behind Fibonacci

His real name was Leonardo Pisano Bogollo from Italy (1170-1250). “Fibonacci” was his nickname. He is famous for Fibonacci series and he also worked for Arab-Hindu numerals like the numbers we use now a days that is 0,1,2,3,4,5,6,7,8,9 and helped spread them in Europe instead of Roman Numerals like I,II,III,IV,V etc.

### Fibonacci sequence generator program in C Programming

This C program with title “Fibonacci Program in C” displays the fib numbers up to n number of terms.

/* Write a C program to show Fibonacci series upto given number of terms entered by user. */ #include <stdio.h> int main() { int i, n, term1 = 0, term2 = 1, nextTerm; printf("Enter the number of terms: "); scanf("%d", &n); printf("The Required Fibonacci Series:\n "); for (i = 1; i <= n; ++i) { printf("%d, ", term1); nextTerm = term1 + term2; term1 = term2; term2 = nextTerm; } return 0; } /*Output: Enter the number of terms: 7 The Required Fibonacci Series: 0, 1, 1, 2, 3, 5, 8 */
