What is wrong w/ this? I get an error on line 10....


#include <iostream.h>

double factorial(int number);

int main()
{
int input;
cout << "Enter a number ";
cin >> input;
cout "Factorial of " << input << " == ";
cout << factorial(input) << endl;
return 0;
}

double factorial(int number)
{
if (number > 1)
return number * factorial(number - 1);
return 1;
}


Thanks!

You need a &lt;&lt; after cout.

Just a small point. Why are you using doubles? If you are looking to be able to store bigger numbers you may want to use a long or a long long(not sure if this is standard, and i've heard it doesnt work with msvc but I havent tried)
