Matrix addition multiplication using operator overloading in C++

Let’s begin to code the Matrix addition multiplication using operator overloading in C++. First of all, we will see how to add a matrix using operator overloading in C++.

Matrix addition using operator overloading in C++

T4Tutorials is the class name. formal_parameters indicates the formal parameter that takes the value from the actual parameters. operator+ indicates that we want to overload the + operator.

//+ operator is overloaded
           T4Tutorials T4Tutorials::operator+(T4Tutorials formal_parameters)
      {
               T4Tutorials t;
               t.u=u;
               t.v=v;
               cout<<t.u;
               cout<<t.v;
               for(int i=0;i<t.u;i++)
                    for(int j=0;j<t.v;j++)
                         t.MyArray[i][i]=MyArray[i][i]+formal_parameters.MyArray[i][i];
                         return t;
      }

Matrix  multiplication using operator overloading in C++

Here, the operator * indicates that we want to overload the + operator.

Now, we will see how to multiply matrix using operator overloading in C++.

//* operator is overloaded
          T4Tutorials T4Tutorials::operator*(T4Tutorials formal_parameters)
     {
               T4Tutorials t;
               t.u=u;
               t.v=formal_parameters.v;
               for(int i=0;i<t.u;i++)
                    for(int j=0;j<t.v;j++)
                        {
                           t.MyArray[i][i]=0;
                           for(int k=0;k<v;k++)
                                  t.MyArray[i][j]+=MyArray[i][k]*formal_parameters.MyArray[k][j];
                        }
                                  return t;
       }
