# Differentiate between procedural programming and object-
oriented programming paradigms.
Ans- Procedural Programming:
Procedural Programming can be defined as a programming model which is derived from structured
programming, based upon the concept of calling procedure. Procedures, also known as routines,
subroutines or functions, simply consist of a series of computational steps to be carried out. During
a program’s execution, any given procedure might be called at any point, including by other
procedures or itself.
Object Oriented Programming:
Object oriented programming can be defined as a programming model which is based upon the
concept of objects. Objects contain data in the form of attributes and code in the form of methods.
In object oriented programming, computer programs are designed using the concept of objects that
interact with real world. Object oriented programming languages are various but the most popular
ones are class-based, meaning that objects are instances of classes, which also determine their
types.
# Discuss advantages and disadvantages of pointers in c++.
Ans- Advantages of pointer
Pointers provide direct access to memory
Pointers provide a way to return more than one value to the functions
Reduces the storage space and complexity of the program
Reduces the execution time of the program
Provides an alternate way to access array elements
Pointers can be used to pass information back and forth between the calling function and called
function.
Pointers allows us to perform dynamic memory allocation and deallocation.
Disadvantages of pointer
Uninitialized pointers might cause segmentation fault.
Dynamically allocated block needs to be freed explicitly. Otherwise, it would lead
to memory leak.
Pointers are slower than normal variables.
If pointers are updated with incorrect values, it might lead to memory corruption.
