static constexpr void assign( char_type& r, const char_type& a );			(since C++17)
static char_type* assign( char_type* p, std::size_t count, char_type a );		(2)

Assigns a character.

1) Assigns character a to character r.

2) Assigns character a to each character in count characters in the character sequence pointed to by p.

Parameters

a	-	character value to assign
r	-	character to assign to
p	-	pointer to a character sequence to assign to
count	-	the length of the character sequence

Return value

1) (none)

2) p

Exceptions

1)

(none)	(until C++11)
noexcept specification: noexcept	(since C++11)

2) (none)

Complexity

1) Constant.

2) Linear in count
