在stdio.h有一个非常重要的东西,文件指针,每个文件都会在内存中开辟一块空间,用于存放文件的相关信息,这些信息保存在一个结构体中: struct _iobuf { char *_ptr; //指向buffer中第一个未读的字节 int _cnt; //记录剩余的未读字节的个数 char *_base;//文件的缓冲 int _flag;//打开文件的属性 int _...
// stringbuf example #include <iostream> // std::cout, std::ostream, std::hex #include <sstream> // std::stringbuf #include <string> // std::string int main () { std::stringbuf buffer; // empty stringbuf //将 stringbuf 对象与 输出流关联,这样,可以利用输出输入,对stringbuf对象进行...
返回destination 的副本,本质为更底层操作的临时内存地址,在实际操作中不建议直接使用此地址,操作完成以后,真正有意义的地址是destination本身。 Example /// Created by zhangrongxiang on 2018/2/10.//#include<string.h>#include<stdio.h>#include<stdlib.h>intmain(){charstr[32] ="I am your GOD";charst...

Thegetlinefunction returns itsistreamargument so that, likethe input operator, it can be used as a condition. For example, wecould rewrite the previous program that wrote one word per line towrite a line at a time instead: getline函数将istream参数作为返回值,和输入操作符一样也把它用作判断条...
