C Program to compute the fibonacci series

      Each number in fibonacci series is obtained by adding the previous two numbers. The base numbers of the series are 0 and 1 i.e., the numbers with what series starts. The third number in the series is the sum of 0 and 1 which is again 1. This program computes the series by stroring the base numbers in an array and then each number is computed by adding the previous two numbers.

fibonacci series program in c



Source Code :

#include<stdio.h>
int main()
{
int fib[15];
int i;
fib[0] = 0;                            // Step 1
fib[1] = 1;                            // Step 1
for(i = 2; i < 15; i++)
fib[i] = fib[i-1] + fib[i-2];           // Step 2
for(i = 0; i < 15; i++)                 // Step 3
printf("%d\n", fib[i]);
return 0;
}

OUTPUT:

0

3
5
8
13
21
34

377

Explanation:

Step 1: The base numbers of the series are stored in fib[0] and fib[1] respectively.

Step 2: From the third number onwards, series is computed by adding the previous two numbers.

Step 3: Now the series is in array which was printed to output screen using for loop.
