Tata Elxsi Engineer Interview Questions and Answers for Freshers

OOPS Concepts are the principles of Object-Oriented Programming that help in designing and implementing software systems.

• Abstraction: Hiding the implementation details and showing only the necessary information.

• Encapsulation: Binding data and functions together to protect data from outside interference.

• Inheritance: Creating new classes from existing ones, inheriting properties and methods.

• Polymorphism: Ability of objects to take on multiple forms or behaviors.

• Example: A car i...read more

C code can be generated in MATLAB using the MATLAB Coder app or by using the 'codegen' function.

• MATLAB Coder app allows users to generate C code from MATLAB code

• The 'codegen' function can be used to generate C code programmatically

• Generated C code can be optimized for specific hardware platforms

• C code can be integrated with other programming languages or software tools

• Example: codegen myFunction -args {arg1,arg2} -config:lib -report

Model in Loop is a simulation technique where a physical system is connected to a computer model for testing and validation.

• Model in Loop (MiL) is a part of the V-Model of software development.

• It involves connecting a physical system to a computer model to test and validate the model.

• MiL is used in various industries such as automotive, aerospace, and defense.

• It helps in identifying and fixing errors in the model before implementing it in the physical system.

• Examples of MiL i...read more

Python has several built-in datatypes including numeric, sequence, and mapping types.

• Numeric types include integers, floats, and complex numbers.

• Sequence types include lists, tuples, and strings.

• Mapping types include dictionaries.

• Python also has boolean and None datatypes.

• Datatypes can be converted using built-in functions like int(), str(), and float().

Software in Loop (SIL) is a testing technique where software is tested in a simulated environment.

• SIL is used to test software components before integrating them into a larger system.

• It involves creating a simulated environment that mimics the real-world environment in which the software will operate.

• SIL can help identify and fix software defects early in the development process.

• Examples of SIL tools include Simulink, LabVIEW, and dSPACE.

• SIL is often used in the automotive an...read more
