This statement means we're declaring some space for the variable called some_number, which can be used to keep integer details.

To compensate, each entry features one or more references into the C++ Programming language (Exclusive Version) (TC++PL) the place yow will discover far more check over here complete explanations and code illustrations. I exploit segment references, rather then web page quantities, so that this glossary can be used along with translations of my guides. It is often wise to examine a whole segment as an alternative to wanting to glean details from the couple of semi-random sentences. For folks keen on The explanations at the rear of the design of C++, most entries also refer to The look and Evolution of C++ (D&E).
