C++

Before writing C, not much attention to the array, so define a, and then prodded the use of the line. But later encountered a problem, resolved after the decision to write such a blog, array without pointers, simply put together well.Now I have

Today's C + + is already a multi-paradigm programming language (MULTIPARADIGM programming language), aProcess form (procedural), object-oriented (object-oriented), function form (functional),The language of the generic form (generic),

========if usage (i) =========* Usage Format:if (an expression)StatementIf the expression is true, the statement is executed, otherwise it is not executed. And if only one statement can be controlled.Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx==========if

Traits in C + + is commonly used in STL to extract type information.For example, define a function template with a template parameter of type T, and return a value of type T.Template typename t::value_type f (T iter) {return *iter;}The return value

1. Specifying exceptionsT funnname (parameterlist) throw (T1, t2,,tn);Where T is the type, parameterlist is the argument list, and the type T1, t2,,tn is the exception that the function throws.2. No exception thrownT funnname (parameterlist) throw ()

This is the first article I've written for the rookie series.Title: Enter a two-dollar lookup tree to convert the two-dollar lookup tree into a sorted doubly linked list. Requires that no new nodes be created, only the pointer is adjusted.For

Template in C + + has a very important position, STL is a lot of use of template written out.I will not list the advantages of the template. Here I just say the principle of the template.when the compiler encounters a template method definition, the

Programmers have difficulties and obstacles. If a new school student asks me if he can be a programmer? I will not hesitate to tell him to put down the program and establish a buddha. Do not step on this line. Although there are many sisters in this
