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

There are multiple ways to do it.

One way is to use the replace function from the algorithm header:

#include <string>

#include <algorithm>

std::string foo = "Hello World";

std::replace( foo.begin(), foo.end(), 'l', 'w'); // replace all 'l' to 'w'
