I'm trying to make this recursive program count how many times it calls itself, and I was going to use a global variable to keep count but eclipse isn't recognizing it for some reason. Here's my code:
#include <iostream> #include <cstdlib> using namespace std; int count = 0; int fib(long int); int main() { long int number; cout << "Enter a number => "; cin >> number; cout << "\nAnswer is: " << fib(number) << endl; return 0; } int fib (long int n) { //cout << "Fibonacci called with: " << num << endl; if ( n <0 ) { cout <<" error Invalid number\n"; exit(1); } else if (n == 0 || n == 1) return 1; else{ count++; return fib(n-1) + fib(n-2);} cout << count; } Whenever I initially declare count, it doesn't even recognize it as a variable, does anybody know the reason for this?
