Question

I have two files Sample.cpp and Main_file.cpp. Sample.cpp has only one namespace n1 which contains the definition of int variable x. I want to print this variable x in my main_file.cpp. How do I go about doing this?

//Sample.cpp_BEGINS

namespace n1
{
    int x=10;
}
//Sample.cpp_ENDS

//Main_FILE_BEGINS

void main()
{
    print x;
}
//MAIN_FILE_ENDS

Thank you for any help you can provide.

You use the fully qualified name of the variable:

int main()
{   
     n1::x = 10;

     return 0;
}
