Everthing About Computer

In a C program, if you create an object of class X, you can get an address using the “this” pointer. The address is available as a local variable not static member functions of X, and its type is const X *. The “this” works because the pointer C instantiates its data members, and keeps a copy of each member function .

Use the “this” pointer to discover the location of a class instance. Like any pointer, which stores an address. GetAddress member function () of C class X returns the address of a particular instance of the class X: public class X {

GetAddress :

X * const () const {

to return this ;

};

access member functions or data members within a class member function with the keyword “this” and the “->” operator. The following example can work without “this->”. But if the library of the matrix has a parent class with member names like “, this-> ‘invoking clear what belongs to the current class, not his father {

[* Matrix class ] int rows, cols :

public ;

Matrix (): rows (0), et al (0 ){

this-> Init ();[* Matrix ();

GetRows ]

}

~ int () const {

return this-> rows ;

}

private: void init

Study ();

};

a class with operator overloading and the use of this study. The following code snippet shows how you can be redefined: X * const this-> operator (){

return this ;

}
