    Fibonacci series in C and  Cplus  Cplus





     In mathematics, the Fibonacci numbers, commonly denoted Fn form a sequence, called the   Fibonacci sequence, such that each number is the sum of the two preceding ones, starting
    from 0 and 1.

    like             0      +      1      =       1
                       1      +      1      =       2
                       1      +      2      =       3
                       3      +      2      =       5
                       5      +      3      =       8
                       8      +      5      =      13
                      13     +      8      =      21 
                      21     +     13     =      34
                      34     +     21     =      55 
                      55     +     34     =      89
                      89     +     55     =      144 
                     144    +     89     =      233  ...........  infinite 
      
             


    The result will be add with previous number and in the same way the series moves forward.

    Logic



      int  first      =  0  ,   second    =  1 ,   next;             //  next means  result   

      next  =   first   +   second; 

      first    =    second;                             //  second value transfer into  first   

      seond    =    next;   



    Output

    0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and so on.....





    Q)  wap in c to find a Fibonacci number.


    #include<iostream.h>

    using namespace std;

    main()
    {
       int n, c, first = 0, second = 1, next;

       cout << "Enter the number of terms of Fibonacci series you want" << endl;
       cin >> n;

       cout << "First " << n << " terms of Fibonacci series are :- " << endl;

       for ( c = 0 ; c < n ; c++ )
       {
          if ( c <= 1 )
             next = c;
          else
          {
             next = first + second;
             first = second;
             second = next;
          }
          cout << next << endl;
       }

       return 0;
    }






    Result




    Enter the number of terms of Fibonacci series you want
    First 10 terms of Fibonacci series are :- 
    0
    1
    1
    2
    3
    5
    8
    13
    21
    34
