Array of objects, C/C++ Programming

Assignment Help:

Array of Objects:

The objects can be declared just like a structure or even a primary data type.  Array of objects may be required to work with large set of data.   When the data is very few objects without array can be used. The declaration of array of object is a follows.

int x; int x[10];  The integer x can store only one data at a time where as array integer x

can store 10 data at time because the size is defined as 10.  This is equivalent to declaring 10 individual integers.

 

class employee

{           char name [30]; float age; public:

void getdata(void);

void putdata(void);

};

 

The class employee has two data members and two functions members.  Earlier an object was produced using as shown

employee manager,foreman,worker;

The three objects are created with different names.  The class employee can created as array of objects as shown below.

employee managers[3]; employee foremen[15]; employee workers[75];

 

 

There are 93 objects of class employee.   There grouped into three manager, foreman, worker.  This is literally means the object store information of 3 managers, 15 foremen, and 75 workers.   Thus array of object will permit group the functionality.   The array element can be accessed using dot operator, just accessing member in the structure.

manager[i].getdata( );

 

The given program will give better understanding of array of objects class employee

{char name[25]; float age; public:

void getdata(void)

{cout<<"Enter Name: "<<"\n";

cin>>name;

cout<<"Enter Age: "<<"\n";

cin>>age;

}

void putdata(void)

{cout<<"Name is "<

cout<<"Age is "<

}

};

 

int main()

{clrscr();

int i;

employee staff[25];

for (i=0;i<25;i++)

{staff[i].getdata();

}

for (i=0;i<25;i++)

{staff[i].putdata();

}

 

cout<<"\n";

getch();

return 0;

}
