How to replace underscore with space in std::string

[Jason Heyes]

What is a nice STL statement/s to replace each occurance of the underscore
character ('_') with a space character (' ') in a std::string? Thanks.

std::replace, perhaps?

#include <algorithm>
#include <iostream>
#include <string>

int main()
{
std::string s("this is a test");

std::replace(s.begin(), s.end(), ' ', '_');
std::cout << s << '\n';
}

What is a nice STL template algorithm to replace each occurrence of some
particular value with some other value in an arbitrary sequence? What do
you think it might be called?
