insert
Syntax:
#include <string> iterator insert( iterator i, const 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, const char& ch ); void insert( iterator i, input_iterator start, input_iterator end );
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 denoted by i, before the character specified by i.
