Problem

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

Solution

std::string doesn't contain such function but you could use stand-alone replace function from algorithm header.

#include 
#include 

void some_func() {
  std::string s = "example string";
  std::replace( s.begin(), s.end(), 'x', 'y'); // replace all 'x' to 'y'
}

Code Snippets

#include <algorithm>
#include <string>

void some_func() {
  std::string s = "example string";
  std::replace( s.begin(), s.end(), 'x', 'y'); // replace all 'x' to 'y'
}
