/* The bzero() function erases the data in the n bytes of the memory
* starting at the location pointed to by s, by writing zeros (bytes containing
* '\0') to that area.
1.	The ft_bzero() function takes two arguments: a void pointer to the memory
	area to be modified and the size of the memory area.
2.	The ft_bzero() function first stores the address of the memory area in a
	char pointer.
3.	The while loop runs as long as n is greater than 0.
4.	The *cptr pointer is incremented by 1 and n is decremented by 1.
5.	The *cptr pointer is set to '\0' and the memory location pointed to by cptr
	is set to '\0'.
6.	The ft_bzero() function returns nothing.
