Here is an excellent collection of 45 free books in PDF format which I found here — "Programming Notes for Professionals" books.

The PDFs contain this on one of their very first pages:

    In fact, "Two statements may be joined by a semicolon, but not a comma" literally applies equally to English and to programming contexts such as C, SQL, and PHP...

    Not quite. At least in C it is perfectly legal to join two statements with a comma. This is most commonly seen when initialising a loop, as in:

            for (i = 0, j = 0; i < k - j; i++)
                a[i] = foo(i, &j);

    No, it isn't. It is legal (in contexts where the comma isn't interpreted as argument separator) to join expressions with a comma, forming another expression. Now in C, a statement may (and often does) consist only of an expression, but not all statements are of that form. For example, the following is a valid sequence of two statements:

    a += b;
    if (a > 10) do_something();

    If it were legal to join statements with a comma, then the following would be legal code, too:

    a += b, if (a > 10) do_something();

    Your compiler will tell you otherwise.
