Difference between C and C++
What do you mean by C?
C is a machine-independent structure or procedural oriented computer language that is widely utilized in a variety of applications. C is a fundamental programming language that can be used to create everything from operating systems (such as Windows) to complicated applications such as the Oracle database, Git, Python interpreter, and many more. Because it serves as the foundation for other programming languages, the C programming language might be referred to as a god's programming language. We can simply learn other programming languages if we already know C. Dennis Ritchie, a legendary computer scientist, created the C programming language at Bell Laboratories. It has a few extra characteristics that set it apart from other programming languages.
What do you mean by C++?
Bjarne Stroustrup created C++ in 1980 at Bell Labs as a special-purpose computer language. C++ is a programming language that is extremely similar to C and is so compatible with C that it can execute 99 percent of C programs without modifying any source code. However, because C++ is an object-oriented programming language, it is a safer and more well-structured programming language than C.
Differences
S No. | C | C++ |
1. | C is a structural programming language that does not support the idea of classes and objects. | C++ is an object-oriented programming language that does support. |
2. | C supports the structural programming language where the code is examined line by line. | C++ is an object-oriented programming language that supports the idea of classes and objects. |
3. | Dennis Ritchie created the C programming language at Bell Laboratories in the 1970s. | Bjarne Stroustrup created the C++ programming language in the 1980s. |
4. | C cannot execute C++ code. | C++ is a programming language that is a superset of C. C++ can execute 99 percent of C code. |
5. | C uses a top-down one. The top-down method divides the primary modules into tasks, which are then divided into sub-tasks, and so on. | C++ uses a bottom-up technique. The bottom-up strategy prioritizes the development of lower-level modules before moving on to higher-level modules. |
6. | Outsiders may readily manipulate data in C because it lacks encapsulation and information hiding. | C++ is a very secure language that provides both encapsulation and data hiding, making it impossible for outsiders to modify its data. |
7. | Functions and data are free entities in the C language. | All functions and data are wrapped in the form of objects in the C++ language. |
8. | Function overloading is a feature that allows you to have more than one function with the same name but varies in the parameters. Function overloading is not supported in C. | It is supported in C++. |
9. | Function overriding is a feature that allows you to customize a function that is previously defined in the base class. Function overriding is not supported in C. | It is supported in C++. |
10. | Reference variables are not supported in C. | Reference variables are supported in C++. |
11. | C provides 32 keywords. | C++ supports 52 |
12. | A namespace is a feature that organizes items such as classes, objects, and functions into a logical hierarchy. The namespace feature in C is absent. | The namespace feature in C++ prevents name clashes. |
13. | Exception handling is not supported directly in C. It must be accomplished through the usage of exception-handling functions. | A try-catch block in C++ offers direct support for exception management. |
14. | In C, the scanf and printf functions are used for input and output. | In C++, the cin and cout functions are used for input and output, respectively. |
15. | For memory allocation, C provides the calloc() and malloc() procedures, as well as the free() function for memory deallocation. | In C++, a new operator for memory allocation and a delete operator for memory de-allocation are available. |
16. | Inheritance is a feature that enables a child class to utilize the parent class's properties. Inheritance is not supported in the C language. | It is supported in C++. |
17. | The <stdio.h> header file is used by C programs. | <iostream.h> header file is used by C++ programs. |
Features
Simple: In the sense that it provides a structured method (to split the issue into sections), a comprehensive collection of library functions, data types, and so on, C is a straightforward language.
Portable: Unlike assembly language, c programs may be run on a variety of computers with few modifications. As a result, C is a machine-independent programming language.
Mid-level programming language: C, on the other hand, is designed for low-level programming. It's used to create system programmers like kernels and drivers. It also has the characteristics of a high-level language. That's why it's referred to be a mid-level language.
Structured Programming Language: C is a structured programming language in the sense that functions may be used to break down a program into smaller chunks. As a result, it is simple to comprehend and alter. Functions also allow you to reuse code.
