Overview
C and C++ are programming languages that are used to create applications. They are two of the most widely used and oldest programming languages. This article will explain the difference between C and C++ programming languages. C++ is a superset of C since it was inspired by and derived from C.
C and C++ are two of the oldest programming languages still in use. Though C++ is a direct descendant of the C language, it has higher efficiency and performance. Each programming language comes with its own set of advantages and disadvantages.
C++ programming language is an upgraded version of the C programming language with the inclusion of object-oriented functionality.
Difference Between C and C++
Some of the common differences between C and C++ are :
- Object-oriented programming: C++ is an object-oriented programming language, whereas C is not. This means that Many features of object-oriented programming language which are present in C++ such as Abstraction, Inheritance, Encapsulation, and Polymorphism are also not available in C language.
- Standard libraries: C++ offers a rich set of standard libraries, including the Standard Template Library (STL), which provides data structures and algorithms for common programming tasks. C, on the other hand, has a limited set of standard libraries and relies more on third-party libraries and system-specific APIs.
- Function overloading: C++ allows for function overloading, which means that multiple functions can have the same name but different parameters. This allows for more flexible and readable code. C, on the other hand, does not support function overloading.
- Operator overloading: C++ also allows for operator overloading, which means that operators such as +, -, *, and / can be redefined to work with user-defined data types. C, on the other hand, does not support operator overloading.
- Namespace declarations: C++ allows for namespace declarations, which help to prevent naming conflicts between different parts of a program. C, on the other hand, does not support namespace declarations.
- Compatibility: C++ is largely compatible with C, meaning that C code can be used in C++ programs, but not necessarily the other way around. However, there are some differences in syntax and features that can cause issues when porting code from C to C++.
Similarities Between C and C++
Some of the common Similarities between C and C++ are:
- Syntax: Both C and C++ share a similar syntax, with many of the same keywords, operators, and programming constructs, including loops, conditional statements, and functions. This similarity in syntax makes it easier for developers to learn both languages.
- Low-level programming: Both C and C++ are low-level programming languages that provide direct access to memory and hardware. This makes them ideal for developing system software and applications that require high performance and low-level access.
- Compiler-based languages: Both C and C++ are compiled languages, which means that the code must be compiled before it can be executed. This allows for better performance and control over system resources.
- Support for pointers: Both C and C++ support pointers, which are variables that hold the memory address of another variable. This allows for more efficient memory management and direct access to hardware resources. However, the use of pointers in both languages can also make the code more error-prone if not used correctly.
What is C Programming Language?
The C programming language is a general-purpose and high-level language that facilitates structured programming. C was later on chosen as a system development language because it generates code that executes almost as quickly as an assembly language code.
The C programming language was created by Dennis Ritchie at Bell Labs in 1972 to allow utilities to run on Unix systems. Because C programs are fast, they allow programmers to manually control computer hardware.
The strength of the C programming language is its performance and its use for coding on a wide range of platforms. Operating systems, interpreters, compilers, and microcontrollers are some of the systems that use the C language for their internal programming.
Features of C Programming Language
Here are the top features of C programming language:
- Efficient: C is known for its efficiency and fast execution speed, making it ideal for developing system software and other applications that require high performance.
- Procedural Language: C follows a top-down approach in solving a problem, which makes it easy to understand and maintain the code.
- Platform-independent: C can be compiled and executed on various operating systems, making it a portable language.
- Static Typing: C is a statically typed language, which helps in catching errors at compile-time and improves code reliability.
- Modular: C supports modular programming, which allows developers to break down the code into smaller, reusable components, making it easier to manage and maintain the code.
Applications of C Programming Language
The top 5 applications of C programming language are following:
- System Programming: C is widely used for developing operating systems, device drivers, and other system software due to its efficiency and low-level programming constructs.
- Embedded Systems: C is often used for developing firmware and embedded systems, such as microcontrollers, routers, and IoT devices.
- Compiler Development: C is often used for developing compilers and other programming tools due to its flexibility and ability to generate efficient code.
- Graphics and Gaming: C is often used for developing graphics and gaming applications due to its performance and low-level access to hardware.
- Database Systems: C is often used for developing database management systems, such as MySQL and PostgreSQL, due to its ability to interact with hardware and low-level constructs.
Advantages of C Programming Language
C is a widely used programming language that has many advantages. One of the main advantages of C is its efficiency and speed. C is a low-level programming language that provides direct access to memory and hardware, making it ideal for developing system software and other applications that require high performance. C is also a portable language that can be compiled and executed on various operating systems, making it a popular choice for developing cross-platform applications. Additionally, C is a mature language with a large community of developers and a rich set of libraries and tools available, making it easy to find resources and support for C programming.
Disadvantages of C Programming Language
Although C has many advantages, it also has some disadvantages. One of the main disadvantages of C is its lack of memory management, which can lead to memory leaks and other memory-related issues if not handled properly. Additionally, C can be a difficult language to learn for beginners due to its low-level constructs and lack of built-in abstractions. Another disadvantage of C is its susceptibility to buffer overflow attacks, which can occur when a program tries to write data beyond the boundaries of an allocated buffer. Finally, C can be a verbose language with a lot of boilerplate code required to perform even simple tasks, which can lead to larger codebases and increased maintenance costs.
What is C++ Programming Language?
C++ was created by Bjarne Stroustrup and was considered the finest version of C when it first appeared in 1985. In 1979, while working at Bell Labs, Bjarne started developing the C++ programming language. He aimed to build a C extension that was more efficient and versatile than the C programming language.
Object-oriented programming (OOPS) is made possible using C++. OOPS is a concept in programming in which we write programs based on the principle of real-world objects. Like every object in the world has its own set of characteristics and functions to perform, similarly, object-oriented programming helps us to implement this approach through programming.
OOPS has four basic principles as given below:
- Abstraction
- Encapsulation
- Inheritance
- Polymorphism
C++ has a low abstraction level and relies on manual memory management. It is lightweight as compared to C programming language and can be used to create apps for a number of different platforms.
Features of C++ Programming Language
Here are the top features of C++ programming language:
- Object-oriented Language: C++ is an object-oriented programming language that supports encapsulation, inheritance, and polymorphism.
