Matrix Mulitplication Addition in Cpp / C++

This Cpp program is for Matrix Multiplication, Addition and Display of Matrix / Array 2D. This is a part of Mumbai University MCA Colleges C++ / CPP Programs MCA. 


In the below program we have used 2 Two Dimensional Arrays to form a Matrix and showed the different operations on Matrix.

#include<iostream.h>
#include<conio.h>
int i,j,k;

class Matrix
{
int a[2][2],b[2][2];
public :
void get_data();
void Show(int [2][2]);
void Add();
void Multi();
};

void Matrix :: get_data()
{
cout<<"Enter data for Matrix A : "<<endl;
for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
cin>>a[i][j];
}
}

cout<<"Enter data for Matrix B : "<<endl;
for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
cin>>b[i][j];
}
}
Show(a);
Show(b);
}


void Matrix :: Show(int x[2][2])
{
cout<<endl<<endl;
cout<<"Array :"<<endl;
for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
cout<<x[i][j];
}
cout<<endl;
}
}

void Matrix :: Add()
{
int c[2][2];
for(i=0;i<2;i++)
for(j=0;j<2;j++)
c[i][j]=0;

for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
c[i][j]=a[i][j]+b[i][j];
}
}

cout<<endl<<"Addittion : "<<endl;
Show(c);
}

void Matrix :: Multi()
{
int c[2][2];
for(i=0;i<2;i++)
for(j=0;j<2;j++)
c[i][j]=0;

for(i=0;i<2;i++)
{
for(j=0;j<2;j++)
{
for(k=0;k<2;k++)
{
c[i][j]=c[i][j]+(a[i][k]*b[k][j]);
}
}
}
cout<<endl<<"Multiplication : "<<endl;
Show(c);
}

void main()
{
Matrix m;
clrscr();
m.get_data();
m.Add();
m.Multi();
getch();
}
