String對象具有類似數組的行為

可以像處理數組那樣來處理String 對象！

1. // String.cpp : Defines the entry point for the console application.
2. //
4. #include "stdafx.h"
5. #include<iostream>
6. #include<string>
8. int main(int argc, char* argv[])
9. {
10. using namespace std;
11. string first_name , last_name;
12. cout<<"Enter your first and last name:";
13. cin>>first_name
14. >>last_name;
15. cout<<endl<<endl;
16. cout<<"your last name is spelled:\n";
17. int i ;
18. for(i = 0; i < last_name.length() ; i++) //用for循環操縱數組
19. {
20. cout<<last_name[i]<<" ";
21. last_name[i] = '-';
22. }
23. cout<<endl;
24. for(i = 0; i < last_name.length() ; i++)
25. {
26. cout<<last_name[i]<<" ";//在每個字母下面顯示一個"-"
27. }
28. cout<<endl;
30. cout<<"Good day "<<first_name<<endl;
31. return 0;
32. }
