=====insert=====
Syntax:

<code>
    #include <string>
    iterator insert( iterator i, Char ch );
    string& insert( size_type index, const string& str );
    string& insert( size_type index, const Char* str );
    string& insert( size_type index1, const string& str, size_type index2, size_type num );
    string& insert( size_type index, const Char* str, size_type num );
    string& insert( size_type index, size_type num, Char ch );
    void insert( iterator i, size_type num, Char ch );
    void insert( iterator i, input_iterator start, input_iterator end );
</code>

The very multi-purpose insert() function either:

  * inserts ch before the character denoted by i,\\
  * inserts str into the current string, at location index,\\
  * inserts a substring of str (starting at index2 and num characters long) into the current string, at location index1,
  * inserts num copies of ch into the current string, at location index,\\
  * inserts num copies of ch into the current string, before the character specified by i.
