1、C+作业61、构建一个复数Complex类，其包含realPart实部和imaginaryPart虚部，提供构造函数可以初始化复数，同时提供实现复数加、复数减、复数乘和复数除的成员函数，并能将相应结果显示出来。测试你所设计的复数类。Complex.h#includeusing std:cout;using std:cin;using std:endl;class Complexpublic: Complex( double, double, double, double ); void complexAdd(); / 加 void complexSub(); / 减 void complexM

2、ul(); / 乘 void complexDiv(); / 除private: double realPart1, realPart2; / 记录实部 double imaginaryPart1, imaginaryPart2; / 记录虚部;Complex.cpp#includeusing std:cout;using std:cin;using std:endl;#includeusing std:setprecision;#include Complex.hComplex:Complex( double r1, double i1, double r2, double i2 ) / 将

3、私有数据结构成员初始化 realPart1 = r1; realPart2 = r2; imaginaryPart1 = i1; imaginaryPart2 = i2;void Complex:complexAdd() /* 实部与实部相加，虚部与虚部相加 cout ( realPart1 + imaginaryPart1 i ) + ( realPart2 + imaginaryPart2 i ) = realPart1 + realPart2 + imaginaryPart1 + imaginaryPart2 i endl; */ /将上述代码格式稍作调整，在负数外面加括号 cout (

4、 realPart1 +; if( imaginaryPart1 0) cout ( imaginaryPart1 ) i; else cout imaginaryPart1 i; cout ) + (; if (realPart2 0) cout ( realPart2 ) +; else cout realPart2 +; if( imaginaryPart2 0) cout ( imaginaryPart2 ) i; else cout imaginaryPart2 i; cout ) = realPart1 + realPart2 +; if(imaginaryPart1 + imag

5、inaryPart2 0 ) cout ( imaginaryPart1 + imaginaryPart2 ) i endl; else cout imaginaryPart1 + imaginaryPart2 i endl;void Complex:complexSub()/* 实部与实部相减，虚部与虚部相减 cout ( realPart1 + imaginaryPart1 i ) - ( realPart2 + imaginaryPart2 i ) = realPart1 - realPart2 + imaginaryPart1 - imaginaryPart2 i endl; */ /

6、 将上述代码格式稍作调整，在负数外加上括号 cout ( realPart1 +; if( imaginaryPart1 0) cout ( imaginaryPart1 ) i; else cout imaginaryPart1 i; cout ) - (; if (realPart2 0) cout ( realPart2 ) +; else cout realPart2 +; if( imaginaryPart2 0) cout ( imaginaryPart2 ) i; else cout imaginaryPart2 i; cout ) = realPart1 - realPart2

7、 +; if( imaginaryPart1 - imaginaryPart2 0 ) cout ( imaginaryPart1 - imaginaryPart2 ) i endl; else cout imaginaryPart1 - imaginaryPart2 i endl;void Complex:complexMul()/* 二项式乘法 cout ( realPart1 + imaginaryPart1 i ) * ( realPart2 + imaginaryPart2 i ) = realPart1 * realPart2 - imaginaryPart1 * imaginar

8、yPart2 + realPart1 * imaginaryPart2 + realPart2 * imaginaryPart1 i endl; */ / 将上述代码格式稍作调整，在负数前加上括号 cout ( realPart1 +; if( imaginaryPart1 0) cout ( imaginaryPart1 ) i; else cout imaginaryPart1 i; cout ) * ( realPart2 +; if( imaginaryPart2 0) cout ( imaginaryPart2 ) i; else cout imaginaryPart2 i; cou

9、t ) = realPart1 * realPart2 - imaginaryPart1 * imaginaryPart2 +; if( realPart1 * imaginaryPart2 + realPart2 * imaginaryPart1 0 ) cout ( realPart1 * imaginaryPart2 + realPart2 * imaginaryPart1 ) i endl; else cout realPart1 * imaginaryPart2 + realPart2 * imaginaryPart1 i endl;void Complex:complexDiv()

10、 if( realPart2 =0 & imaginaryPart2 = 0 ) cout 分母不能为0！ endl; return; /* 乘以除数的共轭复数 cout ( realPart1 + imaginaryPart1 i ) / ( realPart2 + imaginaryPart2 i ) = (realPart1 * realPart2 + imaginaryPart1 * imaginaryPart2) / (realPart2*realPart2 + imaginaryPart2*imaginaryPart2 ) + (- realPart1 * imaginaryPar

11、t2 + realPart2 * imaginaryPart1) / (realPart2*realPart2 + imaginaryPart2*imaginaryPart2 ) i endl; */ / 将上述格式稍作调整，在负数外面加括号 cout ( realPart1 +; if( imaginaryPart1 0) cout ( imaginaryPart1 ) i; else cout imaginaryPart1 i; cout ) / ( realPart2 +; if( imaginaryPart2 0) cout ( imaginaryPart2 ) i; else cou

12、t imaginaryPart2 i; cout ) = setprecision(2) (realPart1 * realPart2 + imaginaryPart1 * imaginaryPart2) / (realPart2*realPart2 + imaginaryPart2*imaginaryPart2 ) +; if( - realPart1 * imaginaryPart2 + realPart2 * imaginaryPart1 0 ) cout ( setprecision(2) (- realPart1 * imaginaryPart2 + realPart2 * imag

13、inaryPart1) / (realPart2*realPart2 + imaginaryPart2*imaginaryPart2 ) ) i endl; else cout setprecision(2) (- realPart1 * imaginaryPart2 + realPart2 * imaginaryPart1) / (realPart2*realPart2 + imaginaryPart2*imaginaryPart2 ) i endl;test_Complex.cpp#includeusing std:cout;using std:cin;using std:endl;#in

14、clude Complex.hint main() double r1, r2, i1, i2; cout 请输入第一个复数的实部和虚部： r1 i1; cout 请输入第二个复数的实部和虚部： r2 i2; Complex C(r1, i1, r2, i2); C.complexAdd(); C.complexSub(); C.complexMul(); C.complexDiv(); return 0;2、对本讲中的Time类，为其增加一个tick成员函数，其作用是将存放在Time对象中的时间递增1秒。应确保你的Time对象始终处于可靠状态。编写测试函数，测试你所修改后的Time类。特别留

15、意： 递增到下一分递增到下一小时递增到下一天Time.h/ Declaration of class Time./ Member functions are defined in Time.cpp/ prevent multiple inclusions of header file#ifndef TIME_H#define TIME_H/ Time class definitionclass Time public: Time(); / constructor void setTime( int, int, int ); / set hour, minute and second void

16、printUniversal(); / print time in universal-time format void printStandard(); / print time in standard-time format void tick( int );private: int hour; / 0 - 23 (24-hour clock format) int minute; / 0 - 59 int second; / 0 - 59; / end class Time#endifTime.cpp/ Member-function definitions for class Time
