What is the major difference between c and c plus plus?

Answer 1

C is an imperative (procedural), structured paradigm language whereas C++ is multi-paradigm: procedural, functional, object-oriented and generic. Both are high-level, abstract languages. While C's design provides constructs that map efficiently to machine code instructions, C++ is more abstract, relying heavily upon object-oriented principals. However, both are equally capable of producing highly-efficient machine code programs. C++ derives almost directly from C thus everything you can do in C you can do in C++ with relatively minor alterations to the source. C++ was originally called C with Classes and that pretty much sums up the main difference between the two languages. However, there are many subtle differences.

One key difference between C and C++ is in the struct data type. In C, a struct can only contain public data members (with no methods). In C++, a struct is similar to a class, combining data and the methods that operate upon that data into a single entity (an object). The only difference between a C++ struct and a C++ class is that class members are private by default whereas struct members are public by default.

Another key difference is that because C++ is object oriented, there is much less reliance upon the programmer to manage memory. Each object takes care of its own memory allocations (including embedded objects), thus the programmer simply creates and destroys objects as needed. Thus C++ is much easier to work with, especially with regards to highly-complex hierarchical structures, but is every bit as efficient as C.

Both languages are highly popular and there are few architectures that do not implement suitable compilers for both. Thus they are both highly portable. However, the object oriented approach to programming gives C++ a major advantage over C in terms of code re-usability, scalability and robustness.

Answer 2

In case of C, importance is given to the steps or procedure of the program while 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

Functions are the building blocks of a C program while objects are building blocks of a C++ program.

C uses scanf & printf while C++ uses cin>> & cout<< as their respective input & output functions

C++ supports Exception Handling while C does not. C does not support it "formally" but it can always be implemented by other methods. Though you don't have the framework to throw & catch exceptions as in C++.

Answer 3

C++ is an object oriented, what is Object oriented is : Object-oriented languages provide abstraction via classes. Classes define the properties and methods of an object type. C is not an object oriented

Answer 4

The biggest difference is in the approach with which programming is done. In c u do top-down programming whereas in c++ u do bottom-up. In c++ the basic thing with which we work is object whereas in c++ we work around functions only.

That is c++ follows OOP while c doesnt.

Answer 5

C++ is C language with added extensions to support object-oriented programming. In general, C++is a superset of C, so that C programs will compile with a C or a C++ compiler. Originally C++ was a pre-processor run before a C compiler.

Answer 6

C++ is object oriented while C is structured. Everything you can do in C you can also do in C++ with little variation. However, you can also mix object-oriented programming concepts with structured and procedural programming in C++.

Answer 7

C++ is an advanced version of C that adds object oriented programing functions.

Answer 8

C++ is an extension of C. Everything you can do in C you can do in C++. But besides some minor syntax differences, the major difference is the inclusion of object-orientated programming.
