Fibonacci Sequence
Fibonacci Sequence
The Fibonacci Sequence is the series of numbers:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
The next number is found by adding up the two numbers before it.
- The 2 is found by adding the two numbers before it (1+1)
- Similarly, the 3 is found by adding the two numbers before it (1+2),
- And the 5 is (2+3),
- and so on!
Example: the next number in the sequence above would be 21+34 = 55

printf("%d %d",f1,f2);
f3=f1+f2;

f1=f2;
f2=f3;
f3=f1+f2;
