C++ program to perform addition of two matrices using operator overloading

This is a C++ program suitable for you. The '+' operator is overloaded here.
The program asks the user to enter the matrices to be added. Then it calls the member functions of the class Matrix to get the matrices and add them by the overloaded '+' operator.

Problem Solution: You can use the following algorithm
1. Define functions for get_matrix(), display_matrix(), and overload the '+' operator.
2. Take user input for matrices.
3. Decide on two variables of the Matrix type.
4. Use the get_matrix() function to receive the matrix
5. Use the display_matrix() function to display the matrices.
6. Add them using the overloaded '+' operator.
7. Print the result.

Operator overloading is a useful feature supported by Object Oriented Programming. Though class is a user defined data type user can easily perform those operations that can be performed on primary data type. So to support this concept Object Oriented Programming use the concept of Operator Overloading. Actually it is function generally called as operator op function. It's syntax is as follows

return data type operator op(argument list);
Here op is replaced by sign of operator which is to be overloaded. Operator function may be simple member function or friend function. While overloading binary operator using simple member function operator function requires only one argument and while overloading binary operator using friend function it requires two arguments.
Following program is solved using simple member function.

Please include iostream.h and conio.h files before declaration of class.
//ADDITION OF TWO MATRIX USING OPERATOR OVERLOADING
#include
#include
class matrix
{
private:
int mat[2][2],add[2][2];
public:
void get(void)
{
for(int i=0;i<2;i++)
{
for(int j=0;j<2;j++)
{
cin>>mat[i][j];
}
}
}
void operator +(matrix a)
{
for(int i=0;i<2;i++)
{
for(int j=0;j<2;j++)
{
add[i][j]=mat[i][j]+a.mat[i][j];
cout< }
cout<<"\n";
}
}
};
void main(void)
{
class matrix p,q;
clrscr();
cout<<"\nEnter four elements of firt matrix\n";
p.get();
cout<<"\nEnter four elements of second matrix\n";
q.get();
cout<<"\nAddition of two matrices is as follows\n";
p+q;
getch();
}

In above program when the statement p+q appears in main function, compiler treat it as p.operator+(q).
