1、三程序分析题阅读以下程序，写出其运行结果。1．#includeinta[10]={1,2,3,4,5,6,7,8,9,10};intfun(inti);voidmain(){inti,s=0;for(i=0;i<=10;i++){try{s=s+fun(i);}catch(int){cout<<"数组下标越界！"<=10)throwi;returna[i];}2．#includevoidf();classT{public:T(){cou

2、t<<"constructor"<classBclass{pu

3、blic:Bclass(inti,intj){x=i;y=j;}virtualintfun(){return0;}protected:intx,y;};classIclass:publicBclass{public:Iclass(inti,intj,intk):Bclass(i,j){z=k;}intfun(){return(x+y+z)/3;}private:intz;};voidmain(){Iclassobj(2,4,10);Bclassp1=obj;cout<

4、<fun()<classBASE{public:virtualvoidgetxy(inti,intj=0){x=i;y=j;}virtualvoidfun()=0;protected:intx,y;};classA:publicBASE{public:voidfun(){cout<<"x="<

5、){cout<<"x="<

6、<"调用基类BASE2的构造函数:"<classT{public:T(){a=0;b=0;c=0;}T(inti,intj,intk){a=i;b=j;c

7、=k;}voidget(int&i,int&j,int&k){i=a;j=b;k=c;}Toperator*(Tobj);private:inta,b,c;};TT::operator*(Tobj){Ttempobj;tempobj.a=a*obj.a;tempobj.b=b*obj.b;tempobj.c=c*obj.c;returntempobj;}voidmain(){Tobj1(1,2,3),obj2(5,5,5),obj3;inta,b,c;obj3=obj1*obj2;obj3.get(a,
