The erase() Function

◀ The rfind() Function▶ getline() versus cin Amazon The erase() function allows you to remove a sequence of characters from a string. A commonly used function is described as follows:

string & erase(int pos = 0, int n = string::npos);

This function simply erases a sequence of characters from index pos, inclusively, over n characters or until the end of the string, whichever comes first.

Here is one example:

string a = "Michael is not everyone’s friend";
a.erase(11, 4);  /* a is “Michael is everyone’s friend” */

You got that right! I am Michael and I am everybody’s friend!
