String replace

Hey everyone,

I'm trying to find a string within a larger string, then replace it with a value. Here is an example (sudocode)?

Code:

---

string 1 = "this is REPLACE_STRING_HERE!";
string 2 = "really cool"

string1.replace("REPLACE_STRING_HERE", string2);

cout << string1 << endl; //outputs this is really cool!

---

How would I go about doing this?

Thanks,

Matt N

Use find to find the location of the search string, then use that location plus the search string's size to get the range to replace with the new string.

You're quite close already. But replace() wants a position and a length or a pair of iterators to specify the position, so you need to use string::find() to get them.

Code:

---

pos = s.find(search_string);
if(pos != string::npos) {
  s.replace(pos, search_string.length(), replacement);
}
