C++

First, C is a language that contains some of the prescribed syntax and structure, but does not include functions that we normally use, such as Prinf () and scanf (), which are provided only by the C standard library. The reason for the existence of

1.c++ has a perfect exception capture mechanism, using the try{} catch () {} mechanism, which is not comparable to the C language2. Common Types of exceptions:Bad_alloc: Request to allocate memory failed, operator new or operator new []Bad_exception:

Contact C language Two months, from the rectification "C Program Design" Introduction, Tripwire knock on the learning of a not clear. Have studied in computer college and Software College, they have been contacted before and through the

Structs in 1.C languages are purely structural, without the concept of access rightsUsing void* to implement generic programming in 2.C language is the base of the implementation of C + + class and template, which is realized by void*.#include

In the program design, in order to deal with the convenience, the same type of a number of variables in the form of an orderly combination. The collection of these ordered, homogeneous data elements is called an array. In the C language, an array is

Linked list nodes in C + + are typically of the same type. So we can do that with templates.#include using namespacestd;template//define a declaration that a template class must haveclassLinknode//The class that represents the linked list node {

Most operators can be overloaded, but there are 5 operators that are not overloaded with the C + + language provisions.1.. (dot operator), usually used to go to a member of an object, but (arrow operator), which can be overloaded2.::(domain operator)

Let me give you a simple explanation. Although not entirely right. But I can make you understand what the effect of out is. OhLet me give you an example. Each method can have only one return value. But you want to have multiple return values, huh.

This is a function pointer and pointer function.This is the invocation of the pointer:Code: #include #include using namespace Std typedef unsigned char unit8_t; extern void Swapdata (unit8_t dat_x, unit8_t dat_y); Int main () { unit8_t x,
