Fibonacci series code in iterative and recursive methods
Iterative method: Use a loop to calculate Fibonacci numbers
Recursive method: Define a function that calls itself to calculate Fibonacci numbers
Example for iterative method: int fib(int n) { int a = 0, b = 1, c; for(int i = 2; i <= n; i++) { c = a + b; a = b; b = c; } return b; }
Example for recursive method: int fib(int n) { if(n <= 1) return n; return fib(n-1...
