In my view, anything the compiler catches is not a bad mistake because the compiler points out exactly where the error is. Those tend to get fixed immediately. The bad mistakes are the ones the compiler doesn't catch. Those are the ones that are likely to creep into production code (code released to the public). Nope.

Shouldn't this say: "This is a bad mistake because the compiler will complain and ask you to fix it." “This is not a bad mistake because the compiler will complain and ask you to fix it.”

“This is a bad mistake because the compiler will complain and ask you to fix it.”

It's useful for using in conjunction with cin and cout so you can type "cin" or "cout" instead of "std::cin" or "std::cout". If you <code>#include <iostream.h></code>, then cin and cout are not defined as being in the std namespace, and you won't need it. However, it's better to <code>#include <iostream></code>, where cin and cout are defined inside the std namespace. In this case, you can use the using statement to make your code simpler and easier to read. using namespace std;

and why you use:


using namespace std;

I don’t use it…
