CPP program to print fibonacci series

The below program prints a Fibonacci Series without recursion. The CPP cout object 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.

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 <iostream.h> using namespace std;   int main() { int n = 0, a = 0, b = 2; int c; int mod;   cout << "Fibonacci series with the first 2 numbers as 0 and 2 is: "; cout << a << ", " << b;   for (n=0; n<10; n++) { c = b + a; cout << ", "; cout << c;   a = b; b = c; } return 0; }

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
