Create a 'MATRIX' class of size m X n

Create a 'MATRIX' class of size m X n. Overload the ‘+’ operator to add two MATRIX objects. Write a main function to implement it.

#include<iostream.h>

#include<conio.h> class mat

{

int m,n,a[20][20]; public:

mat(int x,int y); void readmat(); mat operator +(mat); void display();

};

mat :: mat(int x,int y)

{

m=x;n=y;

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

{

for(int j=0;j<n;j++) a[i][j]=0;

}

}

void mat :: readmat()

{

cout<<"\nenter matrix elements\n"; for(int i=0;i<m;i++)

for(int j=0;j<n;j++) cin>>a[i][j];

}

mat mat:: operator +(mat obj)

{

mat temp(m,n); for(int i=0;i<m;i++) for(int j=0;j<n;j++)

{

temp.a[i][j]=a[i][j]+obj.a[i][j];

}

return temp;

}

void mat:: display()

{

int i,j; for(i=0;i<m;i++)

{

cout<<"\n\n";

for(j=0;j<n;j++)

cout<<"\t"<<a[i][j];

}

}

int main()

{

int m1,n1; clrscr();

cout<<"\nEnter the size(m,n) of matrix: "; cin>>m1>>n1;

mat a(m1,n1),b(m1,n1),c(m1,n1); cout<<"\nEnter martix 1: "; a.readmat();

cout<<"\nEnter matrix 2: "; b.readmat();

c=a.operator +(b); cout<<"\nFirst Matrix :\n"; a.display(); cout<<"\nSecond Matrix :\n"; b.display();

cout<<"\nmatrix 1+matrix 2: "; c.display();

getch(); return 0;

}

********************************OUTPUT**********************************

Enter the size(m,n) of matrix: 2 2

Enter martix 1: enter matrix elements 3 3 3 3

Enter matrix 2: enter matrix elements 4 4 4 4

First Matrix :

3	3
3	3
Second Matrix :
4	4
4	4

matrix 1 + matrix 2:

7	7
7	7
