No semicolon is necessary to end a block. It may be helpful to point out that since a block replaces a single statement (that ends with a semicolon), the block supercedes the use of a semicolon.

The more I get into these lessons the less I know how to use things in the same program. More examples or quizes might be worth looking into.

Cheers :) Now i see a benefit from declare_variable_when_needed instead of all at the top of the function.

Whether you put it in each function or declare it globally so it affects your entire program is really a personal choice. Doing it globally tends to be more convenient, but also increases the potential for naming collisions.

I have a question: how does "using namespace std" work with the nesting? It seems that once written in a block, it is valid for the sub-blocks as well. If it is so, wouldn't it be easier to simply declare it at the beginning rather than several times inside functions? Thanks. Hi Alex,

I'll have to see if there's an update. However, I'm right in the middle of a relocation, so it'll probably take me a while to get to it. My apologies.
