【C语言】模拟实现memcpy库函数

//模拟实现memcpy库函数
#include <stdio.h>
#include <string.h>
void * my_memcpy(void * dst, const void * src, int count)
{
	void *ret = dst;
	while (count--)
	{
		*(char *)dst = *(char *)src;
		dst=(char *)dst+1;
		src=(char *)src+1;
	}
	return ret;
}
int main()
{
	char p[] = "abcdef";
	//char q[] = "abcdef";
	char *a = "fghj";
	my_memcpy(p, a, 2);
	//memcpy(q, a, 2);
	printf("%s\n", p);
	//printf("%s\n", q);
	return 0;
}
