C++使用中几个习惯问题分析

Analysis of Several Habitual Questions in C++ Application

许多人是从C开始了解C++的,许多从C中早已熟悉的函数、指令在C++中仍然好用,就这些函数、指令以及它们的改良:字符串的使用、动态存储分配与撤销、I/O机制、引用、宏定义指令进行分析,指出它们的优劣原因所在,给出了代码。

Most people start to understand C＋＋ from C. Some familiar functions and orders in C language are still used in C＋＋. Analysis has been made on these functions and orders as well as their improvement, such as application of string, dynamic memory allocation and withdrawal, I/O system, reference and macrodefinition order. Their reason of advantage and weakness have been pointed out and their codes have been provided.
