有如下程序:#includeiostreamusingnamespacestd;classMyClass{public:MyClass(intx):val(x){}voidPrint()const{coutconst:val=val\t;}voidPrint(){coutval=valt;}private:intval;};intmain(){constMyClassobj1(10);MyClassobj2(20);obj1.Print();obj2.Print();return0;}程序的输出结果是( )。A.va1=10const:va1=20B.const:va1=10const:va1=20C.const:va1=10val=20D.val=10va1=20

有如下程序:

#include<iostream>

usingnamespacestd;

classMyClass{

public:

MyClass(intx):val(x){}

voidPrint()const{cout<<"const:val="<<<val<<'\t';}

voidPrint(){cout<<"val="<<val<<'t';}

private:

intval;

};

intmain(){

constMyClassobj1(10);

MyClassobj2(20);

obj1.Print();

obj2.Print();

return0;

}

程序的输出结果是( )。

A.va1=10const:va1=20

B.const:va1=10const:va1=20

C.const:va1=10val=20

D.val=10va1=20
