The following are the key differences between C and C++

1. C language is said to be procedural programming language.1. C++ language is said to be object oriented programming language.
2. Data is less secure in C.2. Data is more secure in C++.
3. C language uses top-down approach3. C++ programming language uses bottom-up approach.
4. scanf ( ) and printf ( ) function is used for input/output operations. 4. cin and cout stream are used in C++ for input/output operations.
5. C does not support the concept of function overloading.5. C++ implements the concept of function overloading.
6. C does not have direct support for exception handling and error handling.6. C++ provides the concept of exception handling and thus maintains the normal flow of execution of any program.
7. C does not support the concept of inheritance and re-usability.7. C++ implements program re-usability concept with the help of inheritance.
8. Operator overloading is not supported in C language.8. C++ provides the features of operator overloading.
9. C does not support references, inline functions, templates, etc.9. C++ provides the features of references, inline function, templates, streams for console and file manipulation along with templates.
10.C is a function driven programming language.10. C++ is a object- driven language.

Some more points C vs C++

  • Almost all C programs are C++ programs but vice versa is not true. There are few differences that one should prevent a C program to run under C++ compiler.
  • The most important features C++ adds on to C language are classes, inheritance, function overloading and operator overloading.
  • The object oriented features in C++ allow programmers to build large programs with clarity and ease of maintenance.
  • C++ is easily compatible with the development of editors, compilers, databases and can simulate real-life applications.
  • The C part of C++ gives the language the ability to get close to the machine-level details.
  • C++ programs are easy to maintain and expand. It is very easy to add any new feature to an object based programming rather than traditional programming.
