C program to find Fibonacci series


Hi friends, this lesson is going to show you how to write a C program to print Fibonacci series.

This is the example of Fibonacci series:
0, 1, 1, 2, 3, 5, 8..

Basically the Fibonacci series is finding the next number by adding the first two numbers, for example,

0,1 -> 0 +1 =1 ( 1 is the next number)
0,1,2 -> 1+1 = 2 (2 is the next number)
0,1,2 -> 1+2 = 3
0,1,2,3 -> 2+3 = 5

When the length becomes longer, finding the next number will become harder if you do it manually, but you know we are programmers, we can make it very simple by writing a C program.

Here is the entire C program to find the Fibonacci series:

The above code is self explanatory, just read the comments in it to understand.

When you run this program it will ask you to enter the limit of Fibonacci series that you want to see, for instance if you type 10, so it will generate 10 series of Fibonacci numbers.

This kind of programs often asked in Interviews, so prepare yourselves. Good luck!  Thanks!
