Memory allocation process indicates reserving some part of the memory space based on the requirement for the code execution.
There are two types of memory allocation done in C:
Static memory allocation: The memory allocation during the beginning of the program is known as static memory allocation. In this type of memory allocation allocated memory size remains fixed and it is not allowed to change the memory size during run-time. It will make use of a stack for memory management.
Dynamic memory allocation: The memory allocation during run-time is considered as dynamic memory allocation. We can mention the size at runtime as per requirement. It will make use of heap data structure for memory management. The required memory space can be allocated and deallocated from heap memory. It is mainly used in pointers. Four types of the pre-defined function that are used to dynamically allocate the memory are given below:
malloc()
calloc()
realloc()
free()
Accenture Coding Questions Sum of 7’s Multiple Math
Following are the few points that you can take care of while preparing for the Accenture interview:
Do your homework: Mainly Understand the job role for which you are applying and also learn a few company-related information about Accenture. Research on these things in advance, whether that is exploring the Accenture’s company website or discussing with a friend who works in Accenture.
Think through your answers: While the Accenture interview topics can range from different technical aspects and personal skills, prepare in advance as to how you can answer the questions.

What is run-time polymorphism and how it is achieved in Java?
Run-time polymorphism(dynamic binding or dynamic method dispatch) implies that the call to an overridden method is resolved dynamically during run-time instead of compile-time.
Run-time polymorphism is achieved with the help of method overriding in Java. When a child class(subclass) has the same method name, return type, and parameters as the parent(superclass), then that method overrides the superclass method, this process is known as method overriding.Example: The below example has one superclass Animal and three subclasses, Birds, Mammals, and Reptiles. Subclasses extend the superclass and override its print() method. We will call the print() method with the help of the reference variable of Animal class i.e., parent class. The subclass method is invoked during runtime since it is referring to the object of the subclass and the subclass method overrides the superclass method. As Java Virtual Machine(JVM) decides method invocation, it is run-time polymorphism.
