在線等：C++編程問題求教，謝謝

#include<iostream>

using?namespace?std;

/**********Program**********/

class?MaxMin

{

private?:

int?a,b;

public:

int?MaxCommonDevisor();

int?MinCommonMultiple();

MaxMin(int?a1,int?b1);

};

MaxMin::MaxMin?(int?a1,int?b1)

{

a=a1;

b=b1;

}

int?MaxMin::MaxCommonDevisor()

{

int?t;

if(a>b)?{t=a;a=b;b=t;}

for(int?i=a;i>=1;i--)

if((a%i==0)&&(b%i==0))

return?i;

}

int?MaxMin::MinCommonMultiple()

{

return?a*b/MaxCommonDevisor();

}

/**********?End?**********/

int?main()

{

int?i,j;

cout<<"請輸入兩個整數："<<endl;

cin>>i>>j;

MaxMin?A(i,j);

cout<<"最大公約數："<<A.MaxCommonDevisor()

<<'\t'<<"最小公倍數："<<A.MinCommonMultiple()<<endl;

return?0;

}

還有不懂可以追問
