remove a string from a string in c++ code example

Example 1: removing a character from a string in c++

#include<iostream>
#include<algorithm>

using namespace std;
main() {
   string my_str = "ABAABACCABA";

   cout << "Initial string: " << my_str << endl;

   my_str.erase(remove(my_str.begin(), my_str.end(), 'A'), my_str.end()); //remove A from string
   cout << "Final string: " << my_str;
}

Example 2: erase string c++

string& erase (size_t pos = 0, size_t len = npos);
/*
pos
Position of the first character to be erased.
If this is greater than the string length, it throws out_of_range.
Note: The first character in str is denoted by a value of 0 (not 1).
len
Number of characters to erase (if the string is shorter, as many characters as possible are erased).
A value of string::npos indicates all characters until the end of the string.
