C++实现字符串的拼接

#include

#include

using namespace std;

int main(){

//字符创的拼接

string a = “rtmp://192.168.0.128:1935/live/Test”;

string b = “.flv”;

a.append(b);

cout<<a<<endl;

string str;

str.assign(a); //直接赋值

str.assign(str, 4, str.npos); //赋值给子串

string str1 = “http”;

str1.append(str);

cout << str1 << endl;

system(“pause”);

return 0;

}

输出：

rtmp://192.168.0.128:1935/live/Test.flv

http://192.168.0.128:1935/live/Test.flv
