Replaces the contents of the string.

1) Replaces the contents with a copy of str

2) Replaces the contents with those of str using move semantics. str is in undefined state after the operation.

3) Replaces the contents with those of null-terminated character string pointed to by s.

4) Replaces the contents with character ch

8) Replaces the contents with those of the initializer list ilist.

Parameters

ch	-	value to initialize characters of the string with
str	-	string to be used as source to initialize the string with
s	-	pointer to a null-termanated character string to use as source to initialize the string with
init	-	initializer list to initialize the string with

Complexity

1) linear in size of str

2) constant. If alloc is given and Template:cpp, then linear.

3) linear in size of s

4) constant.

5) linear in size of init
