c语言中strlen函数编译中出现问题,谢谢

#include
#include
int main()
{
char str1[] = "I Love D";
char str2[]="ni shi shui";
char str3[100];
//b[] = a[];
strcpy_s(str1, str2);
strcpy_s(str3, "woaini");
printf("str1=%s\n", str1);
printf("str2=%s\n", str2);
printf("str3=%s\n", str3);
return 0;
}
报错看不懂,请指点一下,谢谢

strcpy__s 换做 strcpy 即可_
