1.需要用到的头文件
#include#include using namespace std;
2. 函数实例
string one("Lottery Winner!"); //直接将字符串赋值给string类
cout << one << endl; //Lottery Winner!
string two(20,'$'); //输入字符个数和字符
cout << two << endl; //$$$$$$$$$$$$$$$$$$$$
string three(one); //初始化为string one
cout << three << endl; //Lottery Winner!
one += " oops!"; //在string one后接字符串
cout << one << endl; //Lottery Winner! oops!
two = "Sorry ,That was "; //为two重新赋值
three[0]='P'; //修改three[0]元素为 P
string four;
four = two + three;
cout << four << endl; //Sorry ,That was Pottery Winner!
char alls[]={"All's well that ends well"};
string five(alls,20); //five初始化为alls的前20个字符
cout << five << "!n"; //All's well that ends!
string six(alls+6,alls+10); //赋值为alls[6]到alls[9](数组名可看成指针)
cout << six << ', '; //well,
string seven(&five[6],&five[10]); //对象名不可看成指针
cout << seven << "...n"; //well...
string eight(four,7,16); //从four[7]开始,将16个字符复制到eight中
cout << eight << "in motion!" << endl; //That was Pottery in motion!
最终输出结果:
Lottery Winner! $$$$$$$$$$$$$$$$$$$$ Lottery Winner! Lottery Winner! oops! Sorry! That was Pottery Winner! All's well that ends! well, well... That was Pottery in motion!
