C++ Program to find the sum of matrices

We input two sets of matrices and the output is obtained simply adding the curresponding elements of the matrices. A game of simple logic.

Program:

//matrix
#include<iostream.h>
#include<conio.h>
class dom
{
int m,n,i,j,a[3][3],b[3][3],c[3][3];
public:
void get();
void check();
void disp();
};
void dom::get()
{
cout<<"enter the order of matrix\n";
cin>>m>>n;
cout<<"enter the elements of first matrix\n";
for(i=0;i<m;i++)
for(j=0;j<n;j++)
cin>>a[i][j];
cout<<"enter the elements of second matrix\n";
for(i=0;i<m;i++)
for(j=0;j<n;j++)
cin>>b[i][j];
};
void dom::check()
{
for(i=0;i<m;i++)
for(j=0;j<n;j++)
c[i][j]=a[i][j]+b[i][j];
};

void dom::disp()
{
cout<<"the sum of matrix is \n";
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
cout<<"\t"<<c[i][j];
}
cout<<"\n";
}
}





void main()
{
clrscr();
dom obj;
obj.get();
obj.check();
obj.disp();
getch();

}
