Lavu Interview Questions and Answers

Constructor initializes an object, destructor cleans up resources. Polymorphism allows objects to be treated as instances of their parent class. Static function belongs to the class, not instances. Volatile keyword indicates a variable may be changed unexpectedly.

• Constructor initializes an object when it is created. Example: 'Car c = new Car();'

• Destructor cleans up resources when an object is destroyed. Example: 'delete ptr;'

• Polymorphism allows a child class to be treated as ...read more

In C++, datatypes have specific ranges and sizes. Embedded systems are real-life examples of using datatypes effectively.

• Datatypes in C++ have specific ranges and sizes to store different types of data efficiently.

• For example, 'int' datatype in C++ typically has a range of -2,147,483,648 to 2,147,483,647.

• Embedded systems use datatypes like 'uint8_t' to efficiently store data in limited memory space.

• Real-life example of an embedded system is a smart thermostat that controls th...read more

Microcontrollers are integrated circuits designed for specific tasks, while microprocessors are general-purpose CPUs. 8051 is a popular microcontroller.

• Microcontrollers are self-contained systems with memory, I/O ports, and timers, designed for specific tasks.

• Microprocessors are general-purpose CPUs that require external components for memory, I/O, and timers.

• 8051 microcontroller is a popular 8-bit microcontroller known for its low power consumption and versatility.

Embedded C is a subset of C language used for programming embedded systems, while Embedded C++ is a subset of C++ language with additional features for embedded systems.

• Embedded C is a subset of C language, with limited features and libraries compared to standard C.

• Embedded C++ is a subset of C++ language, with additional features like classes, inheritance, and polymorphism.

• Embedded C is commonly used for low-level programming in embedded systems, while Embedded C++ is used f...read more

Program to determine if a number is prime or not prime

• Create a function to check if a number is prime or not

• Iterate from 2 to the square root of the number and check for divisibility

• If the number is divisible by any number other than 1 and itself, it is not prime

• Return true if the number is prime, false otherwise

Designed a final year project involving a deep learning model with a block diagram.

• Researched various deep learning algorithms and techniques

• Implemented the chosen algorithm using Python and TensorFlow

• Created a detailed block diagram to illustrate the project workflow

• Tested and evaluated the performance of the deep learning model

• Presented the project findings and results to faculty and peers

Code to generate Fibonacci series using iterative approach

• Initialize an array to store the Fibonacci series

• Start with the first two numbers in the series (0 and 1)

• Use a loop to calculate the next number by adding the previous two numbers

• Continue this process until the desired number of terms is reached
