http://stackoverflow.com/questions/3523145/pointer-arithmetic-for-void-pointer-in-c When a pointer to a particular type (say int, char, float, ..) is incremented, its value is increased by the size of that data type. If a void pointer which points to…

These are two different concepts, you cannot compare them. What the difference between the skunk and the moonlight? Null pointer is a special reserved value of a pointer. A pointer of any type has such a reserved value. Formally, each specific pointe…

delete void pointer是否会有内存泄漏? 看下面一个简单例子 class Test{ public: Test(){ printf ("constructor\n"); } ~Test(){ printf("destructor"); } }; int main(int argc, char *argv[]) { Test *p = new Test(); void *p1 = p; delete p1; printf("the end\n…

1. 动态内存分配的意义 (1)C 语言中的一切操作都是基于内存的. (2)变量和数组都是内存的别名. ①内存分配由编译器在编译期间决定 ②定义数组的时候必须指定数组长度 ③数组长度是在编译期就必须确定的 (3)但是程序运行的过程中,可能需要使用一些额外的内存空间 2. malloc 和 free 函数 (1)malloc 和 free 用于执行动态内存分配的释放 (2)malloc 所分配的是一块连续的内存 (3)malloc 以字节为单位,并且返回值不带任何的类型信息:void* mallo…

首先本文是对参考中三个连接的博客进行的整理,非常感谢三位博主的努力,每次都感叹网友的力量实在太强大了…… 第一章 快速上手 1.  在C语言中用/*和*/来注释掉这段代码,这个实际上并不是十分的安全,要从逻辑上删除一段C代码,最好的办法是使用#if指令:     #if 0         Statement     #endif 2.  其他语言中,无返回值的函数称为过程(procedure). 3.  数组做参数的时候是以引用(reference)的方式传递的,即地址传递.而标量和常量都是传…
