Why there is no object concept in c language?

Answer 1

C is procedural programming language and does not have any object orientated paradigm.

But there is C++ programming language that is C Object-Orientated approach and one of the most popular programming language (rapidly going down).

C++ brought some features to C Programming languages. And one of them is support for classes with fours main OO (Object-Orientated) features: encapsulation, abstraction, inheritance and polymorphism.

Object is an instance of the class, which is created at run-time.

Class is like a template for Object. It tells what kind of data inside it should have and what kind of operations are possible with it (abstraction).

Here is example of the Class:

class Point {

public:

Point();

Point(int x, int y);

~Point();

void setPoint(int x, int y);

int getX();

int getY();

private:

int x;

int y;

};

Point::Point() : x(0), y(0) {

}

Point::Point(int x, int y) {

this->setPoint(x, y);

}

Point::~Point() { }

void Point::setPoint(int x, int y) {

this->x = x;

this->y = y;

}

int Point::getX() {

return this->x;

}

int Point::getY() {

return this->y;

}

Here is example of small program that creates two objects and manipulates them:

#include

using namespace std;

int main() {

Point *a = new Point(1, 2); // Object a

Point *b = new Point(3, 4); // Object b

cout << "a.X = " << a->getX() << "; a.Y = " << a->getY() << endl;

cout << "b.X = " << b->getX() << "; b.Y = " << b->getY() << endl;

delete a;

delete b;

return 0;

}

Answer 2

the computer program written in machine language is object code or object program. the compiler create the object code. the extension of object file is .obj (windos) or .o (unix).

Answer 3

C was created to be a procedural language, C++ is an extension of C with object-oriented features
