Difference among various concepts

 Major Differences Between C And C++

 

C	C++
C follows the procedural programming paradigm	C++ is a multi-paradigm language(procedural as well as object oriented)
In case of C, importance is given to the steps or procedure of the program	C++ focuses on the data rather than the process. Also, it is easier to implement/edit the code in case of C++ for the same reason.
. In case of C, the data is not secured	the data is secured(hidden) in C+
C is a low-level language	C++ is a middle-level language
C uses the top-down approach	C++ uses the bottom-up approach
C is function-driven &  Functions are the building blocks of a C program	C++ is object-driven & objects are building blocks of a C++ program.
We cannot   use function inside the structure	We can use function inside the structure
C uses scanf & printf	C++ uses cin>> & cout<<
C doesnot allows reference varaibles	C++ allows the use of reference variables

 

 

 

 

Difference between a copy constructor and an assignment operator.  

 

Copy Constructor	Assignment Operator
Copy constructor creates a new object which has the copy of the original object.	On the other hand assignment operators does not create any new object. It instead, deals with existing objects.

Difference between "C structure" and "C++  Structure".

                 or

Define classes and structure.

 

 

Class	Structure
User defined data type which contains data and methods to manipulate that data; is known as class.	A structure is a collection of variables, referenced under one name, providing a convenient means of keeping related information together.
Each object is associated with the data of type class with which it is created.	Structure declaration forms a template which can be used to create structure objects.
An object is a variable of a Class.	variables inside a structure are called members.
Class declaration precedes the keyword Class.	Structure declaration precedes the keyword struct.
Eg. class Student {            int rollno;            int marks1, marks2;            public:                       void show(int r); // to print marks                       void sum(int r); // to add the marks };	example: struct address {             char name[80];             char street[80];             char city[20];             char state[20]; };
