The Array object is
meant to store multiple values in a single variable. Object arrays are more
flexible way to solve a problem. It store values of different types in a single
collection. An object array also can store a and reference. Using of array of
object also reduce the runtime performance.
Example – Input
numbers using Array of Objects and print the sum
#include <iostream.h>
class
ObjArr
{
private:
int
num;
public:
void
input()
{
cin>>num;
}
int
disp(int s)
{
cout<<num<<"
";
s=s+num;
return
s;
}
};
void
main()
{
clrscr();
ObjArr
OB[10];
int
i,sum=0;
cout<<"\n\tEnter 10 No. \n";
for(i=0;i<10;i++)
{
cout<<"\t";
}
cout<<"\n\tValues.
";
for(i=0;i<10;i++)
{
sum=OB[i].disp(sum);
}
cout<<"\n\tSum
= "<<sum;
}
Example – Input ‘N’ numbers
using Array of Objects and Sorting the elements using Bubble Sort Technique.
#include <iostream.h>
class
ObjArrSrt
{
private:
int
num;
public:
void
Getdata();
void
Disp();
void
Bsort(ObjArrSrt *, int);
};
void
ObjArrSrt::Getdata()
{
cout<<"\t";
cin>>num;
}
void
ObjArrSrt::Bsort(ObjArrSrt *Bub,int n)
{
int temp;
for(int i=0;i<n;i++)
{
for(int j=0;j<n-i-1;j++)
{
if(Bub[j].num>Bub[j+1].num)
{
temp=Bub[j].num;
Bub[j].num=Bub[j+1].num;
Bub[j+1].num=temp;
}
}
}
}
void ObjArrSrt::Disp()
{
cout<<num<<"
";
}
void main()
{
int n;
ObjArrSrt *Ob ,Obj;
cout<<"\n\tEnter
the Size : ";
cin>>n;
Ob=new ObjArrSrt[n];
cout<<"\n\tEnter
"<<n<<" Elements : ";
for(int i=0;i<n;i++)
{
}
Obj.Bsort(Ob ,n);
cout<<"\n\tOriginal
Elements : ";
for(i=0;i<n;i++)
{
Ob[i].Disp();
}
cout<<"\n\tElements
After Sorting : ";
for(i=0;i<n;i++)
{
Ob[i].Disp();
}
getch();
}
