Wipro Senior Engineer Interview Questions, Process, and Tips

Tosca uses unique identification mechanism called TBox to identify objects and their properties.

• TBox is a unique identifier used by Tosca to identify objects and their properties

• It is a combination of the object name and its properties

• TBox is used to create reusable test cases and reduce maintenance efforts

• Example: TBox for a button on a webpage could be 'Button_Login_Click'

• Tosca also uses XScan to identify objects bas

C++ is an extension of C with object-oriented programming features.

• C++ supports classes and objects while C does not.

• C++ has better support for polymorphism and inheritance.

• C++ has a standard template library (STL) while C does not.

• C++ allows function overloading while C does not.

• C++ has exception handling while C does not.

OOPs stands for Object-Oriented Programming. It is a programming paradigm based on the concept of objects.

• OOPs focuses on creating objects that contain both data and functions to manipulate that data.

• It emphasizes on encapsulation, inheritance, and polymorphism.

• Examples of OOPs languages are Java, C++, Python, etc.

Polymorphism is the ability of an object to take on many forms.

• It allows objects of different classes to be treated as if they were objects of the same class.

• It is achieved through method overriding and method overloading.

• Example: A shape class can have different subclasses like circle, square, triangle, etc. and all of them can be treated as shapes.

• Example: A method can have different implementations in different clas...read more

Data abstraction is the process of hiding implementation details and showing only the necessary information to the user.

• It is a way of organizing complex systems

• It allows users to interact with complex systems without needing to understand the underlying details

• It helps to reduce complexity and increase efficiency

• Examples include object-oriented programming and APIs

A C program to reverse a given string.

• Declare a character array to store the input string.

• Use a loop to iterate through the string and swap the characters.

• Print the reversed string.

Swapping two numbers using macro in C language

• Use a temporary variable to store the value of one number

• Assign the value of the second number to the first number

• Assign the value of the temporary variable to the second number

• Define a macro for swapping the numbers

• Example: #define SWAP(a,b) {int temp; temp=a; a=b; b=temp;}

I have an intermediate skill level in shell casting.

• I have experience in creating shell molds using different materials such as ceramic, resin, and plaster.

• I am familiar with the process of pouring molten metal into the shell mold and the subsequent cooling and solidification process.

• I have worked on projects that required precision and accuracy in shell casting, such as creating intricate metal parts for aerospace app...read more
