Sorting Characters Of A C String

Question

Is there a built-in method for sorting characters in a string, or do I have to construct my own?

for instance:

string word = "dabc";

I would want to change it so that:

string sortedWord = "abcd";

Perhaps char is a better option? 

How would I go about doing this in C++?

Answer 1

The standard library includes a sorting algorithm in the header algorithm>. 

Because it sorts in place, the following will sort your original term.

std::sort(word.begin(), word.end());

Make a copy beforehand if you don't want to lose the original.

std::string sortedWord = word;
std::sort(sortedWord.begin(), sortedWord.end());
