string to char to string

[vindiou]

Why doesn't it print "BCA" ??
How to put "BCA" in b?
Thanks

#include <iostream>

std::string a,b;

int main()
{
   a= "ABC";
   b= a[1] + a[2] + a[0];

   std::cout <<b;
}

You are using the + operator on chars which will do simple integer addition.

You could do something like this instead:

b = {a[1], a[2], a[0]};

This will construct a new string containing the three characters a[1], a[2] and a[0] and then assign it to b.
