Addverb Technologies Interview Questions, Process, and Tips

Polymorphism in C++ allows objects of different classes to be treated as objects of a common superclass.

• Polymorphism is achieved through virtual functions and function overriding.

• It allows for more flexibility and extensibility in code.

• Example: A base class 'Shape' with virtual function 'draw', and derived classes 'Circle' and 'Square' that override 'draw'.

Different motions in a drone are achieved through varying the speed and direction of the propellers.

• Changing the speed of the propellers controls the altitude of the drone.

• Varying the speed of propellers on different sides of the drone allows it to move forward, backward, left, or right.

• Adjusting the speed of the propellers diagonally creates rotational motion for turning.

• Combining these motions enables the drone to pe

PID controller is a control loop feedback mechanism used in systems to control process variables.

• PID stands for Proportional, Integral, Derivative.

• Proportional term responds to the current error.

• Integral term corrects the accumulated error over time.

• Derivative term predicts future error based on current rate of change.

• Tuning involves adjusting the three parameters (P, I, D) to achieve desired system response.

• Example: I...read more

PLC stands for Programmable Logic Controller, used in industrial automation to control machinery and processes.

• PLC is a digital computer used for automation of electromechanical processes.

• It uses a programmable memory to store instructions and specific functions.

• PLCs are commonly used in manufacturing plants, assembly lines, and robotic devices.

• They can be programmed using ladder logic, function block diagrams, or stru...read more

Industrial automation involves the use of control systems such as robots and computers to handle different processes and machinery in an industrial setting.

• Industrial automation helps improve efficiency and productivity by reducing human intervention in repetitive tasks.

• It involves the use of sensors, actuators, and controllers to monitor and control various processes.

• Examples of industrial automation include automated...read more
