string字符串拼接
代码语言：javascript
复制#include<iostream>
using namespace std;
//string字符串拼接
void test()
{
string s1("Good");
string s2 = " Bye";
s1 = s2;
cout << s1 << endl;
s1 = " The World";
cout << s1 << endl;
s1 = '!';
cout << s1 << endl;
//append
string s3 = ("Hello ");
s3.append("The ");
cout << s3 << endl;
string s4("World ");
s3.append(s4);
cout << s3 << endl;
//注意:如果第一个参数填入string类型字符串，就会拷贝第三个字符后面的字符串
/*string s5 = "!!!adadas";
s3.append(s5, 3);*/
s3.append("!!! adbasdas", 5);
cout << s3 << endl;
string s6 = "I Was So Happy Every Day!";
s3.append(s6, 9, 16);
cout << s3 << endl;
}
int main()
{
test();
system("pause");
return 0;
}
