Description
编写一个计算器Counter类，对其重载运算符“+”。用下面的主程序测试，使测试结果正确。
cout << "varThree: " << varThree.getValue() << endl;
return 0;
}
{
public:
Counter(double Val=0.0)
{
itsVal=Val;
}
double getValue()const { return itsVal; }
Counter operator+ (const Counter &v)
{
return Counter(itsVal + v.getValue());
int main()
{
Counter varOne(2), varTwo(4), varThree;
varThree = varOne + varTwo;
cout << "varOne: " << varOne.getValue()<<wenku.baidu.comendl;
cout << "varTwo: " << varTwo.getValue() << endl;
cout << "varThree: " << varThree.getValue() << endl;
return 0;
}
Input
Output
varOne: 2
varTwo: 4
varThree: 6
源代码：
#include <iostream>
using namespace std;
class Counter
}
private:
double itsVal;
};
int main()
{
Counter varOne(2), varTwo(4), varThree;
varThree = varOne + varTwo;
cout << "varOne: " << varOne.getValue()<< endl;
cout << "varTwo: " << varTwo.getValue() << endl;
