Comparison and Differences between C++ and C Language

Comparison and Differences between C and C Language

C and C language are two very common programming languages. They are similar in many aspects, but There are also many differences. This article will compare and illustrate the differences between C and C languages ​​through specific code examples.

  1. Language history and development:
    C language is a general-purpose programming language designed by Dennis Ritchie of Bell Labs in the 1970s. It is a process-oriented structured programming language . C is an object-oriented programming language developed by Bjarne Stroustrup based on the C language in the early 1980s. It extends the functions of the C language and introduces the concepts of classes and objects.
  2. Code example:
    The following is a simple example code that uses C language and C language to implement a function of calculating the addition of two numbers:

C language Example:

#include 

int main() {
    int a = 5;
    int b = 3;
    int sum = a + b;
    printf("Sum is: %d
", sum);
    return 0;
}

C language example:

#include 

int main() {
    int a = 5;
    int b = 3;
    int sum = a + b;
    std::cout << "Sum is: " << sum << std::endl;
    return 0;
}

As can be seen from the above example, the C language uses the printf function to output the results, and C uses the cout object in the iostream library to output the results. This is also one of the differences between C and the C language. C provides a more powerful and flexible standard library.

  1. Object-oriented programming:
    One obvious difference is that C is an object-oriented programming language, while the C language is process-oriented. Object-oriented programming makes C more convenient and maintainable when designing large programs, while the C language is more suitable for simple projects with fewer functions.
  2. Class and object concepts:
    In C, we can use classes to create objects, but there is no concept of classes in the C language. Classes are an important feature of C. They make the organization of code clearer and enable better code reuse and expansion.
  3. Inheritance and polymorphism:
    C supports inheritance and polymorphism, which are important features of object-oriented programming and can achieve code reuse and flexibility. The C language does not support these features and requires programmers to implement them themselves.

To sum up, there are many differences in syntax and features between C and C languages. C is more powerful and flexible, suitable for the development of large projects, while C language is more suitable for small projects and system-level programming. . Which language to choose depends on the needs of the development project as well as personal preferences and experience. I hope this article will be helpful to readers. For students who want to have a deeper understanding of these two languages, they can also improve their abilities through more practice and learning.
