C++ istream::read()方法读文件 ifstream 和 fstream 的 read() 方法实际上继承自 istream 类,其功能正好和 write() 方法相反,即从文件中读取 count 个字节的数据。该方法的语法格式如下: istream & read(char* buffer, int count); 其中,buffer 用于指定读取字节的起始位置,count 指定读取字节的个数。同样...

在C++中,有一个stream这个类,所有的I/O都以这个“流”类为基础的,包括我们要认识的文件I/O,stream这个类有两个重要的运算符: 1、插入器(<<) 向流输出数据。比如说系统有一个默认的标准输出流(cout),一般情况下就是指的显示器,所以,cout<<"Write Stdout"<<'/n';就表示把字符串"Write Stdout"和换行字...
out.write(str1,strlen(str1));//把字符串str1全部写到yyy.yyy中 in.read((unsigned char*)n,sizeof(n));//从xxx.xxx中读取指定个整数,注意类型转换 in.close();out.close(); 四、检测EOF eof();如果到达文件尾返回非0值,否则返回0。
