C + + template class Understanding compiler's compile template processI've often encountered questions about whether it's easy to use a template, and my answer is: "The template is easy to use, but the organization is not easy to write." Look at the

In the C + + programming process, as the project becomes larger, the code will become more and more, and difficult to manage and analyze. As a result, the header (. h) file and the implementation (. cpp) file are separated in C + +, and the concept

Pointers and arrays are not the same, but "many times" we always think pointers and arrays are equivalent. Admittedly, the two can be replaced in some cases, but they cannot be considered appropriate in all cases. The pointers and arrays are not the

1 Introduction C # is a concise, stylish (? ), object-oriented (Object oriented), type-reliable (type-safe) Programming languages. It (pronounced: C sharp) is a development from C + + + +. I think more like Java), and C/s + + is a family language.

In C language applications, such as communications and embedded systems, a software project usually contains a lot of complex functions, to achieve this project is not a programmer alone can be competent, often need a team of effective cooperation,
