首先定义一个类:
class Complex
{
double real;
double virt;
public:
Complex(double r, double v)
{
real = r;
virt = v;
}
};
首先:
构造函数没有返回类型,连void也不许有!!!
如果不幸,在构造函数钱加了void,将出现错误:
error C2380: type(s) preceding 'Complex' (constructor with return type, or illegal redefinition of current class-name?)
然后定义对象,如下定义,
Complex num1 = new Complex(1.0,3.0);
将会出现错误:
error C2440: 'initializing' : cannot convert from 'class Complex *' to 'class Complex'
修改方法:
1)定义指针:Complex *num1 = new Complex(1.0,3.0);
2)不用new,直接构建 Complex num1(1.0,3.0);
好久不写C++代码,
