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

Question

Is there a way to replace all occurrences of a substring with another string in std::string?

For instance:

void SomeFunction(std::string& str) {    str = str.replace("hello", "world"); //< I'm looking for something nice like this } 

Answer 1

#include <boost/algorithm/string.hpp> // include Boost, a C++ library ... std::string target("Would you like a foo of chocolate. Two foos of chocolate?"); boost::replace_all(target, "foo", "bar"); 

Here is the official documentation on replace_all.

Answer 2

Why not implement your own replace?

void myReplace(std::string& str,                const std::string& oldStr,                const std::string& newStr) {   std::string::size_type pos = 0u;   while((pos = str.find(oldStr, pos)) != std::string::npos){      str.replace(pos, oldStr.length(), newStr);      pos += newStr.length();   } }
