C++ Need Help with Displaying Results in Main() DEBUGGING
Hey everyone here is my code
ive tried to display my results with no luck
i get an error
count was not declared in this scope
int main()
{
CircularList<int> channelList(0);
cout << "Value Stored: " << channelList.GetValue() << endl; <--- OVER HERE
}
Can some please help me display my results, or provide a solution much grateful
here is the rest of my program

I strongly suspect one of the following:
- you have mistyped
cout
ascount
in your actual code. - you have mistyped
cout
ascount
in the error message that you provided above, and you haven't got ausing namespace std;
orusing std::cout;
in your actual code. (Alternatively, you can just fully qualifycout
, asstd::cout
.)
[Note: never do using namespace XXX;
in a header file.]
you must qualify the scope of std::cout
, like so:
std::cout << "Value Stored: " << channelList.GetValue() << std::endl;
