【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;}
