Please help with this Fibonacci Code (C++)
#include <iostream>
void fibonacci (int n)
// compute the Fibonacci number F sub n
{
if (n <= 1) cout << n << endl; // F sub 0 = 0 and F sub 1 = 1
else { // compute F sub n
int fn; int fnm2 = 0; int fnm1 = 1;
for (int i = 2; i<=n; i++)
{
fn = fnm1 + fnm2;
fnm2 = fnm1;
fnm1 = fn;
} // end of for
cout << fn << endl;
} // end of else
} // end of fibonacci
void main()
{
int n;
cout << "Input n " << endl;
cin >> n;
cout << "The Fibonacci Number corresp to" << n << " is ";
fibonacci(n);
}

int main()

fibonacci(n);
}> main() function cannot be void. it should be int.

im writing a c++ code and getting stuck on two parts. The first part, when I go to write the customer order out to the file, it writes everything but the price out right. I'll get a weird number like 5.95828e-039 or nan. When I printout to the console it works fine so not sure what's wrong. Second After I write the order out to the file, I then have to go in and read the file and calculate the...
