Inserts characters into the string:

1) Inserts count copies of character ch at the position index

2) Inserts null-terminated character string pointed to by s at the position index. The length of the string is determined by the first null character (effectively calls Traits::length(s).

3) Inserts the first count characters from the character string pointed to by s at the position index. s can contain null characters.

4) Inserts string str at the position index

5) Inserts a string, obtained by str.substr(index_str, count) at the position index

6) Inserts character ch before the character pointed by pos

7) Inserts count copies of character ch before the element pointed to by pos

8) Inserts characters from the range [first, last)

9) Inserts elements from initializer list ilist.

Parameters

index	-	position at which the content will be inserted
pos	-	iterator before which the characters will be inserted
ch	-	character to insert
count	-	number of characters to insert
s	-	pointer to the character string to insert
str	-	string to insert
first, last	-	range defining characters to insert
index_str	-	position of the first character in the string str to insert
ilist	-	initializer list to insert the characters from
Type requirements
- InputIt must meet the requirements of InputIterator.

Return value

1-5) *this

6-9) Iterator following the last inserted character.

Exceptions

1) std::out_of_range if index > size() and std::length_error if size() + count > max_size().

2) std::out_of_range if index > size() and std::length_error if size() + Traits::length(s) > max_size().

3) std::out_of_range if index > size() and std::length_error if size() + count > max_size().

4) Throws exceptions on the following conditions:

a) std::out_of_range if index > size().

b) std::length_error if size() + str.size() > max_size() where ins_count is the number of characters that will be inserted.

5) Throws exceptions on the following conditions:

a) std::out_of_range if index > size().

b) std::out_of_range if index_str > str.size().

c) std::length_error if size() + ins_count > max_size() where ins_count is the number of characters that will be inserted.

6-9) (none)
