Difference between C and C++ programming languages. C++ is developed from C language. So there is no much difference both of them. A number of C programs can be easily compiled in the C++ compiler. All the C operators are valid in C++ and C++ and C expressions are the same. But there are also many differences between them. for more visit: http://stacksol.com/difference-between-c-cpp-programming-languages/

1. What is the Difference Between C and
C++ Programming Languages?
C++ is developed from C language. So there is no much difference both of them. A
number of C programs can be easily compiled in the C++ compiler. All the C operators
are valid in C++ and C++ and C expressions are the same. But there are also many
differences between them.
The major difference between C and C++ is that C is a procedural programming
language and does not support classes and objects, while C++ is a combination of both
procedural and object oriented programming language; therefore C++ can be called a
hybrid language. But although, here we discussed some differences
between C and C++ programming languages.
Difference Between C and C++ Programming
Languages

2.  C++ was developed by Bjarne Stroustrup in 1979 with C++’s predecessor “C with
Classes”.
 C was developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell Labs.
 C++ supports Exception Handling
 C does not support Exception Handling.
 C++ supports functions with default arrangements.
 C does not support functions with default arrangements
 C is a mid-level programming language.
 C++ is a high level language.
 C++ is a superset of C
 When compared to C++, C is a subset of C++.
 In C++, main() function cannot be called through other functions.
 In C, main() function can be called through other functions.
 C++ is an object oriented programming language.
 C is a structural or procedural programming language.
 In C, Functions are the fundamental building blocks.
 In C++, Objects are the fundamental building blocks.
 C provides malloc() and calloc()functions for dynamic memory allocation,
and free() for memory de-allocation.
 C++ provides new operator for memory allocation and delete operator for memory de-
allocation.

3.  C++ supports reference variables.
 C does not support reference variables.
 C does not support function overloading.
 C++ supports function overloading, implying that one can have name of functions with
varying parameters.
 In C++, Data is hidden and can’t be accessed by external functions.
 In C, the data is not secured.
 C++ supports virtual and friend functions.
 C has no support for virtual and friend functions.
 C++ is compatible with generic programming
 C is not compatible
 C follows top down approach.
 C++ follows bottom up approach
 C++ uses cin>> and cout<< for standard input and output.
 C uses scanf() and printf() function for standard input and output.
 In C++, functions can be used inside a structure.
 C does not allow functions to be defined inside structures.
 C++ supports both function and operator overloading.
 C does not support function and operator overloading.

4.  In C++, Encapsulation hides the data to ensure that data structures and operators are
used as intended.
 In C, data are free entities and can be manipulated by outside code. This is because C
does not support information hiding. (Encapsulation Feature)
 C++ supports both pointers and references.
 C supports only Pointers
 C++ has inline function.
 C does not have inline function
 Variable can be defined anywhere in the function.
 In C, variable has to be defined at the beginning, in the function.
 The programs in C language are divided into modules and functions.
 The programs are divided into classes and functions in the C++ programming language.
 The file extension in C is .C
 The file extension in C++ is .CPP
 C does not support object oriented programming; therefore it has no support for
polymorphism, encapsulation, and inheritance.
 Being an object oriented programming language C++ supports polymorphism,
encapsulation, and inheritance.
Understanding the difference between C and C++ and their relative strengths can help
companies leverage them more effectively in their software development projects. This
knowledge alongside expert help provided software development experts could make
C/C++ based projects more successful.
