Sorting Characters Of A C++ String

Question

If i have a string is there a built in function to sort the characters or would I have to write my own?

for example:

string word = \"dabc\";
<         


        

Answer 1

You have to include sort function which is in algorithm header file which is a standard template library in c++.

Usage: std::sort(str.begin(), str.end());

#include 
#include   // this header is required for std::sort to work
int main()
{
    std::string s = "dacb";
    std::sort(s.begin(), s.end());
    std::cout << s << std::endl;

    return 0;
}

OUTPUT:
