一个串行化类通常有一个Serialize成员函数并且使用DECLARE_SERIAL和IMPLEMENT_SERIAL宏。这些在CObject类中有所描述。 重载提取(>>)和插入(<<)是方便的归档编程接口。它支持主要类型和CObject派生类。 CArchive还支持使用MFC Windows套接字类CSocket和CSocketFile编程。IsBufferEmpty成员函数也支持这种使用。如果要了解有...
int do_some_work() { // we allocate an array double *my_array = new double[1000]; // do some work // ... // we forget to deallocate it // delete[] my_array; return 0; } 我们还需要相应的头文件(leaky_implementation.hpp): 代码语言:javascript 复制 #pragma once int do_some_work...
在这种情况下,array方法是NSArray类上的类方法——被NSMutableArray继承——它分配并初始化类的新实例,并将其返回给您的代码。 NSMutableArray *myArray = nil; // nil is essentially the same as NULL // Create a new array and assign it to the myArray variable. myArray = [NSMutableArray array]...
Access Array Elements You can access elements of an array by indices. Suppose you declared an arraymarkas above. The first element ismark[0], the second element ismark[1]and so on. Declare an Array Few keynotes: Arrays have 0 as the first index, not 1. In this example,mark[0]is th...

Type qualifiers can appear in the declaration of an object of array type, but the qualifiers apply to the elements rather than the array itself. You can declare an array of arrays (a "multidimensional" array) by following the array declarator with a list of bracketed constant expressions in ...
The same pthread_t object cannot be used by multiple threads simultaneously. For multiple threads, an array can be created where each element is an ID for a separate thread. e.g. pthread_t th_id[5]; 小实验 1 #include <stdio.h> ...
