- Q5. Explain me about all the data structures you know, tell me their advantages over others and applications
- Ans.
Data structures are fundamental concepts in software engineering that organize and store data efficiently.

Queues: FIFO structure, ideal for managing tasks and scheduling.
Trees: Hierarchical structure, used ...
- Q6. What is the difference between into arr [5] and malloc (5*sizeof (int))
- Ans.
The difference is that 'int arr[5]' creates an array on the stack, while 'malloc(5*sizeof(int))' allocates memory on the heap.
int arr[5] creates an array of 5 integers on the stack, which is a fixed-size memory allocation.
malloc(5*sizeof(int)) dynamically allocates memory on the heap, allowing for variable-size memory allocation.
The memory allocated with malloc must be explicitly freed with free() to avoid memory leaks

- Q3. Explain inheritance and it types
- Ans.
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows a class to reuse code from another class.
Types of inheritance include single inheritance, where a class inherits from only one parent class, and multiple inheritance, where a class inherits from multiple parent classes.
Example: Class B inherits from Class A, so Class B can access
