第六周项目6-复数模板类

你可以使用的main()函数如下。

int main( )
{
    Complex<int> c1(3,4),c2(5,-10),c3;   //实部和虚部是int型
    c3=c1.complex_add(c2);
    cout<<"c1+c2=";
    c3.display( );
    Complex<double> c4(3.1,4.4),c5(5.34,-10.21),c6; //实部和虚部是double型
    c6=c4.complex_add(c5);
    cout<<"c4+c5=";
    c6.display( );
    //下面测试减法、乘法和除法
    ……
    return 0;
}
