I'm owning a give you one review trouble into the brave explain how you didn't war in the air might help you do the answer so you could go and do that
Answer:
The program in C++ is as follows:
#include<bits/stdc++.h>
using namespace std;
class Complex {
public:
int rl, im;
Complex(){ }
Complex(int Real, int Imaginary){
rl = Real; im = Imaginary;
}
};
int main(){
int real, imag;
cout<<"Real: "; cin>>real;
cout<<"Imaginary: "; cin>>imag;
Complex ComplexNum(real, imag);
cout<<"Result : "<< ComplexNum.rl<<" + "<<ComplexNum.im<<"i"<<endl;
}

Light switches
Security cameras
Thermostat
Explanation:
IoT is internet of things that means network of different things that are interconnected through internet and make the decision with the help of Electronic sensors. The sensor sense the data from environment at different times and send this to the cloud (that may be the server). On the basis of this data different devices such as door looks, light switches, security cameras and thermostat take decisions with the help of controllers and change their current state.
<u>For Example</u>
In case of door look, there may be sensor that is sensing the finger prints of the user and after recognizing the person the door will be unlock. If unauthenticated user will try to open the lock a message has been sent to concerned. The training data of the the authorized persons is saved on the cloud, whenever someone tries to access, the data from sensor and cloud send to controller for making comparison and decision. So we can say that Door lock can be controlled IoT.
In case of light switches, there are few sensor available to sense the intensity of life. Different training values of that sensors are stored on the cloud. Whenever these sensors sense the light intensity, they send the data to the cloud contentiously, whenever the data match with darkness intensity, a signal has been send from controller to the switch to ON the lights.
Same as in cameras and Thermostat both are sending data to the cloud and controller. With the help of different image processing techniques and sensor camera will take the decision related to face recognition. Thermostat devices are also on and off by variation of temperature.
Answer:
class Example:
def __init__(self, val):
self.val = val
def __gt__(self, other):
return self.val > other.val
def __sub__(self,other):
return abs(len(self.val) - len(other.val))
def main():
obj1 = Example('this is a string')
obj2 = Example('this is another one')
print(obj1 > obj2)
print(obj1 - obj2)
main()
