basic_string& append( std::initializer_list<CharT> ilist );	(7)	(since C++11)

Appends additional characters to the string.

1) Appends count copies of character ch

2) Appends string str

3) Appends a substring [pos, pos+count) of str. If the requested substring lasts past the end of the string, or if count == npos, the appended substring is [pos, size()). If pos >= str.size(), std::out_of_range is thrown.

4) Appends the first count characters of character string pointed to by s. s can contain null characters.

5) Appends the null-terminated character string pointed to by s. The length of the string is determined by the first null character.

6) Appends characters in the range [first, last)

7) Appends characters in the initializer list ilist.

Parameters

count	-	number of characters to append
ch	-	character value to append
first, last	-	range of characters to append
str	-	string to append
s	-	pointer to the character string to append
init	-	initializer list with the characters to append

Return value

*this

Complexity

1) linear in count

2) linear in size of str

3-4) linear in count

5) linear in size of s

6) linear in distance between first and last

7) linear in size of init
