string str="abdese";
char ch = str[3];
string s("What we have here is a failure to communicate");
string sub = s.substr(21);
cout << "The original string is " << s << endl;
cout << "The substring is " << sub << endl;

char ch = str[3];
string s("What we have here is a failure to communicate");
string sub = s.substr(21);

#include
void main()
{
char *str = "abdese";
char e = str[3];
printf("%c", e);
}
字符串可以当数组用。
void main()
{
char *str = "abdese";
char e = str[3];
printf("%c", e);
}
