C program to show overloading of matrix operator:

Write a program for matrix operator overloading.

class matrix{

 

                private :

                int x[2][2];

 

                public:

                void show();

 

                matrix operator + (matrix);

                matrix(int a,int b,int c,int d);//consructor

 

                matrix() //default constructor

                {

                for (int i= 0;i<2;i++)

                for(int j=0;j<2;j++)

                x[i][j]=0;

                }

       ~matrix()

       {

       }

       };

                 void matrix ::show()

                 {

                 for (int i= 0;i<2;i++)

                                for(int j=0;j<2;j++)

                                                 cout <<"\n"<

 

                  }

                  matrix:: matrix (int a,int b,int c,int d)//constructor definition

                                   {

 

                                                   x[0][0]=a;

                                                   x[0][1]=b;

                                                   x[1][0]=c;

                                                   x[1][1]=d;

                                   }

 

 

                 matrix   matrix :: operator +(matrix b)

                    {

                    matrix c;

                    for (int i= 0;i<2;i++)

                                for(int j=0;j<2;j++)

                                    c.x[i][j]=x[i][j] + b.x[i][j];

                     return c;

                     }

 

       void main()

                 {

                  matrix a,b,c;

                  clrscr();

                  b=a=matrix(1,2,3,4);

                  c=a+b; //c=a.operator + (b);

                                 //here b is the argument passed to the memeber function

                                 //where a is the invoking object of the operator + function

                                 //whereas in friend function a anb b are treated as

                                 //arguments

                  c.show();

                  getch();

                  }
