有如下程序:
Private type stu
X as string
Y as integer
End type
Private Sub Command1_Click()
Dim a as stu
a.x=”ABCD”
a.Y=12345
print a
End Sub
程序运行时出现错误,错误的原因是
A)Type定义语句没有放在标准模块中
B)变量声明语句有错
C)赋值语句不对
D)输出语句print不对
第1题:
有如下程序: #include<iostream> using namespace std; class Base { private: char c; piblic: Base(char n):c(n){} ~Base() { cout<<C; } }; class DeriVed:public Base { private: char c; public: Derived(char n):Base(n+1),c(n){} ~Derived() { cout<<c; } }; int main() { Derived obj('x'); return 0; } 执行上面的程序将输出
A.xy
B.yx
C.x
D.y
第2题:
有以下程序: #include<iostrearn> using namespace std; class sample { private: int x; static int y; public: sample (int A) ; static void print (sample s); }; sample::sample(int A) { x=a; y+=x; }
A.x=10,y=20
B.x=20,y=30
C.x=30,y=20
D.x=30,y=30
第3题:
有如下程序:
include<iostream>
using namespace std;
class Monitor{
public:
Monitor(char t):type(t){ }
void Print( )const
{cout<<"The type of monitor is"<<type< private:
char type;
};
class Computer{
public:
Computer(int i,char C) :______{}
void Print( )const
{eout<<"The computer is"<<id<<endl;mort.Print( );}
private:
int id;
Monitor mon;
};
int main( ){
const Computer myComputer(101,'B');
myComputer.Print( );
return 0;
}
请将程序补充完整,使程序在运行时输出:
The computer is 101
The type of monitor is B

A.X,Y
B.a,b
C.X,X
D.Y,Y
