Function Implementation help!

closed account (S3TkoG1T)

I'm working with this function below:

 void print(std::string arr[], int n, std::ostream &os=std::cout);

I'm trying to implement this function, using the third parameter as the left-hand operand so instead of writing,
cout << "{"
I use
os << "{".
However I'm getting a GCC error that my "os was not declared in this scope".

Has anybody dealt with this before? I'm absolutely lost!
