2. Welcome guys !

3. Smashing C++ !!

4. Classes & Structures

5. Structures !

6. Structures
•Holds pieces of data

7. Structures
•Holds pieces of data

8. Structures
•Holds pieces of data
struct structName{
……….members
……..
} its objects(if any) ;

9. Structures
•A member could be from a struct type .
struct Date{
int month;
int day;
int year;
} x,y ;
struct PersonInfo
{
double height;//in cm
int weight;//in kg
Date birthday;
};

10. Structures
•A member could be from a struct type .
struct Date{
int month;
int day;
int year;
} x,y ;
struct PersonInfo
{
double height;//in cm
int weight;//in kg
Date birthday;
};
You can define Like this or like this : Date x,y ;

11. Structures
•A member could be from a struct type .
struct Date{ int month; int day; int year; } x,y ; struct PersonInfo { double height;//in cm int weight;//in kg Date birthday; };
Don’t forget comma !

12. Structures
struct structName{
……….members
……..
} its objects(if any) ;
…..
……
int main()
{
….
}
•This declaration must be Global , to be seen by all functions.

13. Structures
•It’s a type ! So it means :
struct Date{
int month;
int day;
int year;
}
void get(Date x, int count )

14. Structures
struct Date{
int month;
int day;
int year;
};
Date get (int z , int count )
•It’s a type ! So it means :

15. struct Date{
int month;
int day;
int year;
} x,y ;
struct PersonInfo
{
double height;//in cm
int weight;//in kg
Date birthday;
};
Structures
PersonInfo christoph ;
christoph.height=170;
christoph.weight=70;
christoph.birthday.month=10 ;
christoph.birthday.day=3 ;
christoph.birthday.year=1978 ;
•To reach to its members :

16. struct Date{ int month; int day; int year; } x,y ; struct PersonInfo { double height;//in cm int weight;//in kg Date birthday; };
Structures
PersonInfo christoph ;
christoph.height=170;
christoph.weight=70;
christoph.birthday.month=10 ;
christoph.birthday.day=3 ;
christoph.birthday.year=1978 ;
•To reach to its members :

17. Structures
•Initialize :
struct Date{
int month;
int day;
int year;
} x,y ;
struct PersonInfo
{
double height;//in cm
int weight;//in kg
Date birthday;
};

Note :
Unlike Array , when you initialize , if you pass the number of members !
You will have an Error !

38. & To save the memebers values !

39. Output:

40. Classes !

43. Classes
•It’s like a Struct.
•Its members could be Functions and data
• it supports( information hiding, data abstraction, and encapsulation )

44. Classes
•It’s like a Struct.
•Its members could be Functions and data
• it supports( information hiding, data abstraction, and encapsulation )
•private, only seen in the current class(for class functions) , unseen out of class !
• public, seen everywhere (in current class and out of class)
•We use two things in classes :

45. Classes

•Mostly in each class , you might have get(privateto variables )and set(variablesprivate) functions

Don’t forget!

51. •You can definitions them here !
•But it’s better not !

54. Returned type

56. •Output:

57. Classes
