模拟实现strcpy

include<stdio.h>
include<stdlib.h>
char* my_strcpy(char* dest, const char* src)
{
 char* ret = dest;
 while (*dest = *src)
 {
  dest++;
  src++;
 }
 return dest;
}
int main()
{
 char arr1[] = { 0 };
 char arr2[] = "abcde";
 char* ret = my_strcpy(arr1, arr2);
 printf("%s", arr1);
 system("pause");
 return 0;
}
