Differences between C and C++ Explained by ISM UNIV
Let us check basic introduction about the programming languages and Differences between C and C++ Explained by ismuniv, C and C++. The programming language C++ is derived exclusively from the programming language C and it is always termed as super set of the C. In fact, people used to call C++ in earlier days as C language with classes. What is making here C++ a super set is its class’s addition and inheritance mechanism with class objects to the other classes. Also, it is possible to compile your C programs successfully using C++ compilers too. Importantly, expressions in C++ and C are same too besides keeping all the C operators as valid with C++. So, these basics itself are clearly signifying the similarities between both programming languages.
Let us see differences between both programming languages:
- C is a procedural programming language while C++ is not because it is an object orient language.
- There will be no virtual functions in C while C++ uses successfully the concept of the virtual functions in it.
- The C is lacking polymorphism and this is an important OOPS feature. C++ uses the concept of the polymorphism in it.
- C doesn’t have operator overloading while C++ features mainly operator overloading in it.
- Program language C uses Top Down process or approach in the programming design and C++ adopts Bottom UP approach in it.
- Namespace feature lacking in C and C++ uses it in order to avoid name collision.
- C allows global variable multiple declarations while C++ does not.
- Input and Output functions are used differently in these languages.
- Mapping between function and data is complicate procedure with C while C++ maps it wisely using “objects”.
- It is easy to call main () functions with other function(s), but C++ cannot.
- It is imperative to define all variables at the beginning of the scope in C and C++ allows this declaration of the variables anywhere within scope.
- Inheritance feature cannot be seen with C while C++ features it.
- C supports primitive as well as built-in data types and C++ supports user define and built-in type data.
- Exceptional handling is not possible with C and C++ does it through Catch block and Try.
