并发症(complex symptoms)
第1题:
Big Screen Complex has the__________ (comfortable) seats.
第2题:
____________
[A] complex
[B] comprehensive
[C] complementary
[D] compensating
第3题:
有以下程序 #include <iostream> using namespace std; class Complex { public: Complex (double r=0, double i =0 :re(r) ,im (i) {} double real() const {return re;} double imag() const { return im;} Complex operator + (Complex c} const {return Complex(re+c.re, im+c.im);} privane: double re,im; }; int main { Complex a =Complex (1,1)+Complex(5); cout<<a.real()<<'+'<<a.imag() << 'i' <<endl return 0; } 程序执行后的输出结果是
A.6+6i
B.6+1i
C.1+6i
D.1+1i
第4题:
下面是复数类complex的定义,其中作为友元函数重载的运算符“--”的功能是将参数对象的实部减1,然后返回对该对象的引用;请补充完整。
class complex
{
private:
int real;
int imag;
public:
complex(int r=0,int i=0):real(r),imag(i){}
void show ()
{
cout<<real<<(imag<0?"-":"+")<<imag<<'i';
}
______;
};
complex& operator -- (complex &c)
{
c.real --;
return c;
}
第5题:
使用VC6打开考生文件夹下的工程test38_3。此工程包含一个test38_3.cpp,其中定义了类complex,但类的定义并不完整。请按要求完成下列操作,将程序补充完整。
(1)添加类complex的无参数的构造函数的定义,将私有成员real和imag都初始化为0。请在注释“//**1**”之后添加适当的语句。
(2)添加类complex的带两个参数的重载构造函数,两个参数r和i都是double类型,要求将r赋值给私有成员real, i赋值给私有成员imag,同时允许调用时参数i可是省略,请在注释“//**2**”之后添加适当的语句。
(3)完成类complex重载加法函数的定义,该函数直接返回一个类complex的对象,同时把参数对象c的实部real和虚部imag分别与当前对象对应部分分别相加,请在注释“//**3**”之后添加适当的语句。
(4)完成类complex的友元函数print的定义,使其以格式“real+imagi”输出,请在注释“//**4**”之后添加适当的语句。
源程序文件test38_3.cpp清单如下;
include <iostream.h>
class complex
{
public:
// ** 1 **
// ** 2 **
{
real=r;imag=i;
}
complex operator+(complex & c);
friend void print(complex &c);
private:
double real,imag;
};
complex complex::operator+(complex & c)
{
// ** 3 **
}
// ** 4 **
cout<<c.real<<"+"<<c.imag<<"i"<<endl;
}
void main( )
{
complex c1(2.0,3.0),c2(4.0,-2.0),c3;
c3=c1+c2;
print(c3);
c3=c3+complex(3.5);
print(c3);
}

第13题:
( 13 )有如下复数类的声明,请补充完整。
class complex{
double real; // 实部
double imag; // 虚部
public:
complex(double x , double y){
real=x;
imag=y;
}
perator+(complex c){// 重载加法运算符 “ + ”
return complex(___________)
}
};
第14题:
表达式type(3)in(int,float,complex)的值为__________。
第15题:
有如下程序: #include <iostream> using namespace std; class Complex { double re, im, public: Complex(double r, double i): re(r), im(i) {} double real() const {return re;} double image() const {return im,} Complex& operator +=(Complex a) { re +=a.re; im +=a.im; return *this; } }; ostream& operator << (ostream& s, const Complex& z) { return s<<'('<<z.real()<<','<<z.image()<<')'; } int main() { Complex x(1,-2), y(2,3); cout << (x+=y) << endl; return 0; } 执行这个程序的输出结果是( )。

第16题:
有下列程序: #include<iostream> using namespace std; class Complex { double re,im; public: Complex(double r,double i):re(r),im(i){} double real()const{retum re;} double image()const{return im;} Complex& operator+=(Complex A) { r

肺原发综合征(pulmonary primary complex)
第21题:
junctional complex
第22题:
第23题:
However, doctors treat the symptoms with the cure for CFS.
Currently, doctors treat the symptoms because there is no cure for CFS.
But doctors know there is no cure and because of that they treat the symptoms.
Since there is no cure for CFS, doctors treat the symptoms without the cure.
When there are symptoms, doctors treat them without the cure for CFS.
