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;
    		}
