2.1 string对象常见构造(constructor) 我们研究几个比较重要的 1、string() 构造空的string对象,即空字符串 2、string(const char* s) 用C-string来构造string类对象 其实相当于将常量字符串拷贝到str中 3、string(const string&s) 拷贝构造函数 拷贝构造其实是深拷贝,因为str1和str2指向的是不同的空间 4、str...
As of JDK 1.1, the preferred way to do this is via the String constructors that take a java.nio.charset.Charset, charset name, or that use the platform's default charset. Java documentation for java.lang.String.String(byte[], int, int, int). Portions of this page are ...

string Dup(char c, int length) { string s=""; for (int i=0; i<length; i++) s +=c; return s; } 今天在一本书中看到 string 的一个构造: new string(char c, int length), 居然完全和我的 Dup 功能一样。这样 string space10=new string(' ', 10);string line20=new string('-',...
