(1)编写一个 row*col 的矩阵类,定义构造函数、复制构造函数;
(2)重载运算符“+”和“-”实现矩阵的相应运算;
(3)重载运算符<<实现矩阵数据的输出。
(1)头文件 matrix.h
#include
using namespace std;
class Matrix{
private:
int row;
int col;
int size;
double* data;
public:
Matrix(int r,int c){
row = r;
col = c;
size = row * col;
data = new double[size];
cout<<"请输入"<> data[i*row+j];
}
}
}
~Matrix(void){
delete []data;
}
Matrix (const Matrix& M)
{
col = M.col;
row = M.row;
size = M.size;
data = new double [M.size];
for(int i=0; i|
(2)源文件 main.cpp
#include
#include "matrix.h"
using namespace std;
int main(void){
Matrix M1(4,4);
Matrix M2(4,4);
Matrix M3 = M1;
Matrix M4 = M1 + M2;
Matrix M5 = M3 - M2;
cout << "M1:"<
template
class Matrix{
private:
int row;
int col;
int size;
T* data;
public:
Matrix(int r,int c){
row = r;
col = c;
size = row * col;
data = new T[size];
cout<<"请输入"<> data[i*row+j];
}
}
}
顺便说下模板的实例化如下
Matrix M(4,4);
