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

Complexity

1) Constant.

2) Linear in count.
