Remove a word with find() and erase

#include <iostream>
#include <string>
#include <cctype>
#include <algorithm>
#include <vector>
using namespace std;
int main()
{
  string strA("This is a test.");
  // Create an iterator to a string.
  string::iterator itr;
  cout << "Remove " larger".\n";
  itr = find(strA.begin(), strA.end(), "l");
  strA.erase(itr, itr+7);
  cout << strA << "\n\n";
  return 0;
}

string.erase(6,9)

#include <iostream>
#include <string>
using namespace std;
int main()
{
  string str1("String handling C++ style.");
  string str2("STL Power");
  cout << "Initial strings:\n";
  cout << "str1: " << str1 << endl;
  cout << "str2: " << str2 << "\n\n";
  // demonstrate erase()
  cout << "Remove 9 characters from str1:\n";
  str1.erase(6, 9);
  cout << str1 <<"\n\n";
  return 0;
}
Initial strings:
str1: String handling C++ style.
str2: STL Power
Remove 9 characters from str1:
String C++ style.

Three forms of erase() function from a string

#include <iostream>
#include <string>
using namespace std;
int main()
{
    string word1 = "Game";
    string word2("Over");
    string word3(3, "!");
    string phrase = word1 + " " + word2 + word3;
    cout << phrase << endl;
    phrase.erase(4, 5);
    cout << "The phrase is now: " << phrase << endl;
    phrase.erase(4);
    cout << "The phrase is now: " << phrase << endl;
    phrase.erase();
    cout << "The phrase is now: " << phrase << endl;
    return 0;
}

Use erase to remove all characters from (and including) location 6 through the end of string1

#include <iostream>
using std::cout;
using std::endl;
#include <string>
using std::string;
int main()
{
   string string1( "abcedfghijklmnopqrstuvwxyz" );
   
   cout << "Original string:\n" << string1 << endl << endl;
   string1.erase( 6 );
   cout << "Original string after erase:\n" << string1
      << "\n\nAfter first replacement:\n";
             
   return 0;
}
Original string:
abcedfghijklmnopqrstuvwxyz
Original string after erase:
abcedf
After first replacement:
