ASSIGNMENT - 12
Program: Write a C++ Program to design a class to represent a matrix. The class
should have the functionality to insert and retrieve the elements of the matrix.
Code:
#include<iostream>
using namespace std;
class matrix{
public:
int row, col;
int arr[100][100]; //max size;
//parameterised constructor.
matrix(int r, int c){
row = r;
col = c;
}
//getter
void setvalue(){
for(int i = 0; i < row; i++){
for(int j = 0 ; j < col ; j++){
cout<<"Enter value for row "<< i <<" column "<< j <<": ";
cin>>arr[i][j];
}
}
}
//print function
printmatrix(){
for(int i = 0; i < row; i++){
for(int j = 0; j < col; j++){
cout << arr[i][j] << " ";
}
cout << endl;
}
}
};
int main(){
int r, c;
cout<<"Enter number of rows: ";
cin>>r;
cout<<"Enter number of columns: ";
cin>>c;
output:
matrix m(r,c);
m.setvalue();
m.printmatrix();
return 0;

Program: Write a C++ program to design a class representing complex numbers
and having the functionality of performing addition & multiplication of two
complex numbers using operator overloading.
Code:
#include <iostream>
using namespace std;
class Complex {
int real, imag;
public:
// Parameterized constructor
Complex(int r = 0, int i = 0) {
real = r;
imag = i;
}
// Overload + operator for complex number addition
Complex operator+(Complex const& obj) {
Complex temp;
temp.real = real + obj.real;
temp.imag = imag + obj.imag;
return temp;
}
// Overload * operator for complex number multiplication
Complex operator*(Complex const& obj) {
Complex temp;
temp.real = real * obj.real - imag * obj.imag;
temp.imag = real * obj.imag + imag * obj.real;
return temp;
}
// Function to display the complex number
void print() {
cout << real << " + " << imag << "i" << endl;
}
};
int main() {
Complex c1(2, 3); // First complex number
Complex c2(4, 5); // Second complex number
Complex c3 = c1 + c2; // Add the two complex numbers
cout << "Sum: ";
c3.print(); // Print the sum
Complex c4 = c1 * c2; // Multiply the two complex numbers
cout << "Product: ";
c4.print(); // Print the product
return 0;

friend function. The following overloaded operators should work for a class
vector.
