How can I use Boost's replace_all function to find and replace substrings in a std::string?

How do I Search/Find and Replace in a standard string?

In the context of std::strings, there are various approaches to find and replace substrings. The original question explores one such technique.

Using Boost's replace_all Function

One efficient method is to utilize the boost::algorithm::replace_all function provided by the Boost C library. This approach is particularly advantageous due to its simplicity and flexibility:

#include <boost/algorithm/string.hpp> // Include Boost

std::string target("Would you like a foo of chocolate. Two foos of chocolate?");
boost::replace_all(target, "foo", "bar");

In this example, the target string contains multiple occurrences of the substring "foo." By employing boost::replace_all, we can replace all instances of "foo" with "bar." This function efficiently modifies the string in-place, updating all occurrences of the specified substring.
