Thread: 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

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);
}
