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.
1 2 3 4 5 6 7 8 9 10 11 12 13 | //+ 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++.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | //* 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; } |
