What error? Just dumping a load of code does not help us to discover what your problem is. Please edit your question and add full details of the problem.

In addition to what Richard said, when editing your post, please remove any unnecessary code. Just post what is relevant to the actual problem. All else is just noise.

Hi, it seems like you are getting an error because you are not using the correct namespace or scope for cout. cout is defined within the std namespace, so you need to either use std::cout or add a using namespace std; directive before your main function. For example:

#include
using namespace std;

int main()
{
cout << "Hello world";
return 0;
}

or

#include

int main()
{
std::cout << "Hello world";
return 0;
}

You can read more about namespaces and cout here:https://stackoverflow.com/questions/15359589/cout-is-not-a-member-of-std-cout-was-not-declared-in-this-scope[^], 'cout' was not declared in this scope [FIXED][^] or https://stackoverflow.com/questions/15185801/cout-was-not-declared-in-this-scope[^] Best regards, Mia from CodeIT
