一个关于strcpy_s的问题
#include<cstring>#include<iostream>
using namespace std;
class score
{int no;
char name[8];
int math;
int phi;
int data;
int ave;
public:
void write(int a,int b,int c,int d,char*p)
{no=a;math=b;phi=c;data=d;strcpy_s(name,p);name[sizeof(name)-1]='\0';}
void average()
{ave=(math+phi+data)/3;}
void display(score m)
{cout<<"学号"<<m.no<<"姓名"<<name<<"数学"<<m.math<<"物理"<<m.phi<<"数据结构"<<m.data<<"平均分"<<m.ave<<endl;}
};
int main()
{score s[3];
s[1].write(1001,80,70,60,"zhou");
s[1].average;
s[2].write(1002,90,80,85,"chen");
s[2].average;
s[3].write(1003,70,75,89,"wang");
s[3].average;
s[1].display(s[1]);
s[2].display(s[2]);
s[3].display(s[3]);
}
下面是报错信息：
E:\C程序\类和对象\2.cpp(13) : error C2065: 'strcpy_s' : undeclared identifier
E:\C程序\类和对象\2.cpp(22) : warning C4551: function call missing argument list

为什么头文件加了cstring，strcpy还没法用？warning C5551：---啥意思？我用的c++6.0
