思路很清晰的c++课件。例子很简明

例2.22 引用举例

#include <iostream.h>

int &max(int &num1,int &num2);
int &min(int &num1,int &num2);

void main()
{	int n1,n2;
	cout<<"Enter two numbers:";
	cin>>n1>>n2;
	max(n1,n2)=0;
	cout<<"\nAftrer putting zero in largest,then numbers are:"
		<<n1<<" and "<<n2<<endl;
	cout<<"Enter two numbers:";
	cin>>n1>>n2;
	mix(n1,n2)=0;
	cout<<"\nAftrer putting zero in smallest,then numbers are:"
		<<n1<<" and "<<n2<<endl;
}

int &max(int &num1,int &num2)
{	return  (num1>num2?num1:num2);
}

int &min(int &num1,int &num2)
{	return  (num1<num2?num1:num2);
}
