1、对负数类重载取负运算符和取正运算符，即单目“—”和“+”。//complex.hclasscomplex{private:doubleimag,real;public:complex(doubler=0.0,doublei=0):real(r),imag(i){}complexoperator-();complexoperator+();voiddisplay();};//complex.cpp#include#include"complex.h"usingnamespacest

2、d;complexcomplex::operator-(){complextemp;temp.real=0.0-(real);temp.imag=0.0-(imag);returntemp;}complexcomplex::operator+(){complextemp;temp.real=0.0+real;temp.imag=0.0+imag;returntemp;}voidcomplex::display(){cout<=0)cout<<"+"<

3、elsecout<#include"complex.h"usingnamespacestd;voidmain(){complexc(2,-6.8),negtive,positive;positive=c;cout<<"取正之后的结果是："<

4、"<
