Hi,
IIRC, some release of GCC moved objects like "cout" from the global namespace to the std:: namespace.
So for code that use to look like this:
#include <iostream>
void foo() { cout << "Hello, World!" << endl;}I now have the code look like this (by adding the 2nd line):
#include <iostream>
using namespace std;
void foo() { cout << "Hello, World!" << endl;}Alternatively, if I didn't want to use the statement "using namespace std;", I could instead write code as follows (by adding the "std::" prefix where necessary):
#include <iostream>
void foo() { std::cout << "Hello, World!" << std::endl;}
Hope this helps, Christian
