1 #include <iostream>
2 #include <string>
3 #include <cstring>
4 using namespace std;
5
6 int main()
7 {
8 string s = "hello world!";
9 const char *str = s.c_str();
10 char ch[100];
11 int i = 0;
12 while(*str != '\0')
13 {
14 ch[i++] = *str++;
15 }
16 cout << ch << endl;
17 return 0;
18 }
请将10行中的数组初始化，或者退出while循环后增加语句ch[i] = '\0' 。
另外，可以有：s + ' a' + str + "welcome" + ch 。想想string类的特征。
