Are C language and C++ the same language?

Are C language and C the same language?

C language and C are two popular programming languages ​​that share a common origin, but have some obvious differences in syntax, features, and uses. While they are similar in some ways, they are not identical.

1. Origin and development history
   The C language was developed by Dennis Ritchie of Bell Labs in the early 1970s. It is a procedural language mainly used for system programming and low-level development. C language is simple and efficient, and is widely used in operating systems, compilers, embedded systems and other fields. C is an object-oriented programming language introduced by Bjarne Stroustrup in the early 1980s. C adds object-oriented features to the C language, provides more powerful abstraction capabilities and code reusability, and is suitable for more complex software development.
2. Grammar features
   C language is a procedural language. The program is composed of functions and has no concepts of classes and objects. It uses structured programming methods, focuses on data and operations, and is suitable for scenarios that require high efficiency and low-level control. The following is a simple C language code example:

#include <stdio.h>

int main() {
    int num1 = 5;
    int num2 = 10;
    int sum = num1 + num2;

    printf("The sum is: %d", sum);

    return 0;
}

C is an object-oriented programming language that supports the concepts of classes and objects, and provides features such as encapsulation, inheritance, and polymorphism. C code examples are as follows:

#include <iostream>

class Calculator {
public:
    int add(int num1, int num2) {
        return num1 + num2;
    }
};

int main() {
    Calculator calc;
    int result = calc.add(5, 10);

    std::cout << "The sum is: " << result << std::endl;

    return 0;
}

3. Application fields
   Due to the efficiency and low-level control capabilities of C language, it is widely used in operating systems, embedded systems, drivers and other fields. Due to its object-oriented nature, C is suitable for developing complex applications, such as graphical interfaces, game development and large-scale system design. In practical applications, one or both of the two languages ​​are often selected for development according to needs.

To sum up, although the C language and C have a common historical origin, they have large differences in syntax, features and application fields, so they cannot be regarded as the same language. Choosing which language to use depends on specific project needs and development goals.
