Yes, strings can be sorted as well. The below code:
-------------------
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

int main(){
  string hw="Hello World!";
  sort(hw.begin(), hw.end());
  cout << hw << endl;
}
--------

Outputs:

 !HWdellloor

Note that to invoke sort() function you need to include <algorithim>
header.

Thanks,
