Need guidance for " this"keyword

[xxRoshanxx]

Hey everyone, I need help on how to use the "this" pointer. And how can it be used in file handling stuff. . (like that seekg and seekp )pls can someone help me with an example! .?

A less crucial use is to write explicitly clear code:

T Foo::bar( const Foo & other ) {
  this->gaz = other.gaz;
  // the this is optional. One could have
  gaz = other.gaz;
  // instead, but more explicit code is, well, explicit 

If you for some reason use ambiguously same name for member and argument, then the this is necessary:

T Foo::bar( const Bar & gaz ) {
  this->gaz = gaz;
  // the left side is member gaz
  // the right side is function argument 

There are times, when you do need to refer to the object:

Foo & Foo::operator= ( const Foo & other ) {
  // something
  return *this;
}
