你这基础还得努力呀，尤其是 int i =1;
 程序代码：#include <iostream> using namespace std; class stu { public: stu() { num_ = 0; name_[0] = '\0'; } stu( int no, const char* name ) { num_ = no; strcpy( name_, name ); } int outnum() const { return num_; } int& outnum() { return num_; } private: int num_; char name_[10]; }; int main() { int& (stu::*p_stu_outnum)() = &stu::outnum; stu s[2]; for( int i=0; i<2; ++i ) { cout << "请输入学号:"<<endl; cin >> (s[i].*p_stu_outnum)(); } return 0; } |
程序代码：#include <iostream>
using namespace std;
class stu
{
private:
int num;
char name[10];
Date bir;
public:
stu(int n,char *nam)
{
num = n;
strcpy (name , nam);
}
stu(){}
int outnum()
{
return num;
}
};
void mian()
{
stu s[2];
int (stu::*num1)() ;
num1 = stu :: outnum;
for ( int i =1 ; i < 2 ; i++)
{
cout << "请输入学号:"<<endl;
cin >> (s[i].*num1) ();
}
}
using namespace std;
class stu
{
private:
int num;
char name[10];
Date bir;
public:
stu(int n,char *nam)
{
num = n;
strcpy (name , nam);
}
stu(){}
int outnum()
{
return num;
}
};
void mian()
{
stu s[2];
int (stu::*num1)() ;
num1 = stu :: outnum;
for ( int i =1 ; i < 2 ; i++)
{
cout << "请输入学号:"<<endl;
cin >> (s[i].*num1) ();
}
}
