What will be the output of the following C++ code?
#include <iostream>
#include <string>
using namespace std;
class complex
{
    int i;
    int j;
        public:
    complex(){}
    complex(int a, int b)
        {
            i = a;
        j = b;
    }
 
    complex operator+(complex c)
        {
        complex temp;
        temp.i = this->i + c.i;
        temp.j = this->j + c.j;
        return temp;
    }
 
    void show(){
        cout<<"Complex Number: "<<i<<" + i"<<j<<endl;
    }
};
 
int main(int argc, char const *argv[])
{
    complex c1(1,2);
    complex c2(3,4);
    complex c3 = c1 + c2;
    c3.show();
    return 0;
}
  • a)
    Complex Number: 4 + i6
  • b)
    Complex Number: 2 + i2
  • c)
    Error
  • d)
    Segmentation fault
Correct answer is option 'A'. Can you explain this answer?

What will be the output of the following C++ code?#include <iostrea...
As we have defined in the class complec that when we add the two objects of the class complex then add those two complex numbers and show() displays that result.

What will be the output of the following C++ code?#include <iostrea...
Explanation:
- The code defines a class `complex` with two integer data members `i` and `j`.
- It also defines a parameterized constructor and an overloaded `+` operator for adding two complex numbers.
- The `show` method is used to display the complex number in the format `Complex Number: a + ib`.
- In the `main` function, two complex objects `c1` and `c2` are created with values (1, 2) and (3, 4) respectively.
- The `operator+` function is called when `c1 + c2` is performed, resulting in a new complex object `c3` with values (4, 6).
- Finally, the `show` method is called on `c3` to display the sum of the two complex numbers.
Therefore, the output of the code will be:

Output: Complex Number: 4 + i6
