Question

In every language that I can think of, except C++, the function Replace essentially replaces all pieces of a string, whereas C++’s string class does not support simple operations like the following:

string s = "Hello World";
s = s.Replace("Hello", "Goodbye");
echo s; // Prints "Goodbye World"

This seems the most common use of any type of string replace function, but there doesn’t seem to be a standard replace function in C++. Am I missing something here?

EDIT: I’m aware that there’s not a built-in replace function like this in the standard library — I’m wondering if there is a more or less standard implementation made from standard algorithms or something of that sort.

Answer 1

You’re not missing anything, its not in the standard library.
You can either write that yourself using find(), replace() etc. or use an implementation like replace_all() from Boosts string algorithm library.
