C program to print fibonacci series

by

The below program prints a Fibonacci Series without recursion and with recursion. The C printf statement is used to output the result on the screen. A series is called as a Fibonacci series if the each next term of the series is a sum of previous two numbers.

C program to print fibonacci series
a, b, c, d, e

c = a+b
d = b+c
e = c+d

For example,
0 2 2 4 6 10 16 26

Code:

#include <stdio.h>
 
void main()
{
 
int n = 0, a = 0, b = 2;
int c;
int mod;
 
printf ("Fibonacci series with the first 2 numbers as 0 and 2 is: ");  
printf ("%d, %d", a, b);  
 
for (n=0; n<10; n++)  
{  
c = b + a;  
printf ( ", ");
printf ( "%d",c);
 
a = b;  
b = c;  
}
}

Output

Fibonacci series with the first 2 numbers as 0 and 2 is: 
0, 2, 2, 4, 6, 10, 16, 26, 42, 68, 110, 178
