## Infosys Technical Interview Questions

Let’s discuss the most asked Infosys coding interview questions.

Can we implement multiple inheritances in Java?

Java doesn't directly support the multiple inheritances concept. But we can achieve multiple inheritances with the help of an interface. Yes, It is possible to implement multiple interfaces into our program.

Explain pointers in C++.

A pointer is a variable that stores the address of another variable of the same data type. Any data type, as well as user-defined data types such as class, structure, and others, can be used to produce pointers. It enables variable passing via address references. Consider the following scenario:

int c = 37; int *ptr = &c; cout << ptr;

The address of c will be stored in ptr. For example, the ptr value is the address of x. We can get the value stored at the address addressed by ptr using ptr (i.e., 37). The ptr(pointer) operator is also known as the dereference operator. Pointers can be used for a variety of purposes. To point to a variable that exists within the memory. To keep track of the addresses of memory blocks that are dynamically allocated.

What are the disadvantages of the Waterfall model?

=> Working software is only developed at the end of the life cycle. => Not appropriate for complex or object-oriented programs. => It isn't easy to assess progress within each level. => It is not recommended for projects with standard requirements that may result in a significant risk of change. As a result, this concept is fraught with danger and ambiguity. => Because integration is done towards the end, it is challenging to discover any commercial or technology bottlenecks or issues earlier.

Explain the Agile model.

Agile is a software development paradigm that uses the iterative approach to help teams offer value to their customers faster, with higher quality, fewer errors, and a greater capacity to adjust to change. Instead of the "big bang" launch, an agile team releases a product in small increments. Continuous evaluation of requirements, plans, and results ensures that teams have a natural mechanism for responding quickly to change.

The most popular Agile techniques are Scrum and Kanban.
