int main()

{

bool running = true;

string pre_sum;

int fib_th;

while (running)

{

cout << "Which Fibonacci number would you like me to compute ? ('q' to quit) ";

cin >> pre_sum;

fib_th = atoi(pre_sum.c_str());

if ( pre_sum[0] == 'q' )

{

running = false;

}

else if ( fib_th >= 0 )

{

if ( fib_th % 10 == 1 )

cout << "The " << fib_th << "st Fibonacci number is " << fibb(fib_th) << endl;

else if ( fib_th % 10 == 2 )

cout << "The " << fib_th << "nd Fibonacci number is " << fibb(fib_th) << endl;

else if ( fib_th % 10 == 3 )

cout << "The " << fib_th << "rd Fibonacci number is " << fibb(fib_th) << endl;

else

cout << "The " << fib_th << "th Fibonacci number is " << fibb(fib_th) << endl;

}

}

cout << "Goodbye." << endl;

return 0;

}

I have to define the funtion:

int fibb(int num_in);

in a new file to have the program compute whatever fibonacci number is requester by the user.

any suggestions?

Thanks.
