C LANGUAGE TUTORIAL-(1)-FIBONACCI SERIES

FIBONACCI SERIES

Fibonacci series is a set of numbers that starts with one or zero(both correct)followed by one, in which each successive element in the sequence is adding by two previous element in the sequence.this sequence is named after the italian mathematicain "fibonacci" .so in the fibonacci series the  1st element  is 0 and 2nd element is 1 so the 3rd element will be 1 now for next element will be the sum of the previous two element that area 1 and 1 ,so the 4th element will be 2,so by applying  this logic we are getting the fibonacci series as:-                       0 1 1 2 3 5  8 13 21 34....
