Question

C++。。设计一个矩阵类，要求矩阵类中重载运算符加（+），主函数定义类对象并调用重载的运算符

求解答，求代码，

Answer 1

#include<iostream>
using namespace std;
const int R=3, C=4;
class Matrix{
double a[R][C];
public:
Matrix operator+(Matrix& d)
{
Matrix temp;
for(int i = 0 ; i<R; i++)
for(int j = 0 ; j<C ; j++)
temp.a[i][j]=a[i][j]+d.a[i][j];
return temp;
}
void Input()
{
cout<<"请输入" <<R <<"*" <<C <<"矩阵:";
for(int i = 0 ; i<R ; i++)
for(int j = 0; j<C ; j++){
cout <<"a[" <<i <<"][" <<j <<"]=";
cin>> a[i][j];
}
}
void display(){
for(int i = 0 ; i<R; i++){
for(int j = 0 ; j<C ; j++)
cout <<a[i][j] <<" ";
cout <<endl;
}
}
};

int main()
{
Matrix m1,m2,m3;
m1.Input();
m2.Input();
m3=m1+m2;

cout <<"Matrix m1:\n";
m1.display();
cout <<"\nMatrix m2:\n";
m2.display();
cout <<"\nMatrix m3:\n";
m3.display();
return 0;
}
