输入10个学生的姓名、学号、成绩，然后输出其中不合格者。
代码如下
编译 连接时出错，如下：--------------------Configuration: sy5_17 - Win32 Debug--------------------
Linking...
sy5_17.obj : error LNK2001: unresolved external symbol "int * fail" (?fail@@3PAHA)
sy5_17.obj : error LNK2001: unresolved external symbol "char * name" (?name@@3PADA)
sy5_17.obj : error LNK2001: unresolved external symbol "int * num" (?num@@3PAHA)
sy5_17.obj : error LNK2001: unresolved external symbol "int * grade" (?grade@@3PAHA)
Debug/sy5_17.exe : fatal error LNK1120: 4 unresolved externals
执行 link.exe 时出错.
sy5_17.exe - 1 error(s), 0 warning(s)
目前只学到数组，后面什么指针还有其他什么的还没学...
程序代码：#include <iostream>
using namespace std;
void cheek();
char name[];int num[],grade[],fail[];
int k=0;
int main()
{
int i;
cout<<"请输入姓名、学号、成绩，中间以空格隔开："<<endl;
for(i=0;i<=9;i++)
{
cin>>name[i]>>num[i]>>grade[i];
cout<<endl;
}
cheek();
cout<<"不合格者为："<<endl;
for(i=0;i<=k;i++)
cout<<name[fail[k]]<<num[fail[k]]<<grade[fail[k]]<<endl;
return 0;
}
void cheek()
{
int i;
for(i=0;i<=9;i++)
{
if(grade[i]<60)
fail[k]=i;k++; //记录不及格者的数组下标
}
}
using namespace std;
void cheek();
char name[];int num[],grade[],fail[];
int k=0;
int main()
{
int i;
cout<<"请输入姓名、学号、成绩，中间以空格隔开："<<endl;
for(i=0;i<=9;i++)
{
cin>>name[i]>>num[i]>>grade[i];
cout<<endl;
}
cheek();
cout<<"不合格者为："<<endl;
for(i=0;i<=k;i++)
cout<<name[fail[k]]<<num[fail[k]]<<grade[fail[k]]<<endl;
return 0;
}
void cheek()
{
int i;
for(i=0;i<=9;i++)
{
