C++

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:

The function for dynamically allocating memory in the C language is the malloc () function, and the corresponding memory-deallocation function is the function. Their function prototypes were: void *malloc ( size_t size );// Header file is Stdlib.h

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

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)

Pointer learning for multiple arraysDefining a two-bit arrayint date[4][5];Indicates that all members of this array are of type intint date[4][5] = {// {1, 2, 3, 4, 5},// {1, 2, 3, 4, 5},// {1, 2, 3, 4, 5},// {1, 2, 3, 4, 5}//};or int date[4][5] = {1

After iOS4, the introduction of the code block features, in the GCD will be used frequently, so decided to take a good look at the code block document, the piece summed up. Explain the code block from the beginning.1. Declaring and using code blocks

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,
