The Fibonacci numbers or Fibonacci series or Fibonacci sequence has first two numbers equal to 1 and 0 and the further each number is consist of the addition of previous two numbers

1st number = 0

2nd number = 1

3rd number = 0+1= 1

4th number = 1+1= 2

5th number = 1+2= 3

And so on.

### C++ Program

#include<iostream> using namespace std; int main() { int range, first = 0, second = 1, fibonicci=0; cout << "Enter Range for Terms of Fibonacci Sequence: "; cin >> range; cout << "Fibonicci Series upto " << range << " Terms "<< endl; for ( int c = 0 ; c < range ; c++ ) { if ( c <= 1 ) fibonicci = c; else { fibonicci = first + second; first = second; second = fibonicci; } cout << fibonicci <<" "; } return 0; }
