13) Create a class Matrix and Write a C++ program with following functions: i. To accept a Matrix ii. To display a Matrix iii. Overload unary minus ‘–‘ operator to calculate transpose of a Matrix iv. Overload binary multiplication '*’ operator to calculate multiplication of two matrices .
#include<iostream.h>
#include<conio.h>
class matrix
{
int i,j,k,a[3][3],b[3][3],c[3][3];
public:
void accept();
void display();
void operator -();
void operator *(matrix);
};
void matrix::accept()
{
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
cin>>a[i][j];
c[i][j]=0;
}
}
}
void matrix::display()
{
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
cout<<" "<
}
cout<<"\n";
}
}
void matrix::operator -()
{
