指针作为函数的参数，引用作为函数的参数

个人觉得引用作为函数的参数比指针作为函数的参数好用多了。

下面举个简单的例子：

引用作为函数的参数：

#include<iostream>
#include<string>
using namespace std;
class student
{
    private:
        char name;
        char   sex;
        int   num;
    public:
        student(char &name1,char &sex1,int &num1)
        {
            name=name1;
            sex=sex1;
            num=num1;
        }
        void print()
        {
            cout<<name<<endl;
            cout<<sex<<endl;
            cout<<num<<endl;
        }
    };
    class student1:public student
    {
        private:
            char major;
        public:
            student1(char &name1,char &sex1,int &num1,char &major1):student(name1,sex1,num1)    
            {
                major=major1; 
            }
            //void print()    
        };
    int    main()
        {
            char a,b,d;
         int  c;
            cin>>a>>b>>c>>d;
            student1 m(a,b,c,d);
            m.print();
            return 0;
        }
指针作为函数的参数
#include<iostream>
#include<string>
using namespace std;
class student
{
    private:
        char name;
        char   sex;
        int   num;
    public:
        student(char *name1,char *sex1,int *num1)
        {
            name=*name1;
            sex=*sex1;
            num=*num1;
        }
        void print()
        {
            cout<<name<<endl;
            cout<<sex<<endl;
            cout<<num<<endl;
        }
    };
    class student1:public student
    {
        private:
            char major;
        public:
            student1(char &name1,char *sex1,int *num1,char *major1):student(name1,sex1,num1)    
            {
                major=*major1; 
            }
            //void print()    
        };
    int    main()
        {
            char a,b,d;
         int  c;
            cin>>a>>b>>c>>d;
            student1 m(&a,&b,&c,&d);
            m.print();
            return 0;
        }
