How to replace all occurrences of a character in string?

Question

What is the effective way to replace all occurrences of a character with another character in std::string?

Answer 1

I thought I'd toss in the boost solution as well:

#include 

// in place
std::string in_place = "blah#blah";
boost::replace_all(in_place, "#", "@");

// copy
const std::string input = "blah#blah";
std::string output = boost::replace_all_copy(input, "#", "@");
