How to alphabetically sort a string with uppercase and lowercase characters?

Question

This is what I have, so far.

#include <iostream>
#include <algorithm>
using namespace std;

int main() {
string str="zXxybac";
sort(str.begin(), str.end());
cout<<str;
return 0;
}

Output:
Xabcxyz

what I want is to arrange the 'X' after 'x'.
