C++ program of data insertion at end in array

In this program we will learn how to enter data on the last index of array by assigning new memory location.


//Code starts 
#include<iostream>
#include<conio.h>
using namespace std;

class array{
private:
int a[10],size,data,index;
public:
array(); //constructor
void create();
void print();
void insert();
};

array::array()
{
size=5;
index=size; 
}

void array::create()
{
    for(int i=0;i<size;i++)
    {
    cout<<"Enter data at index ["<<i<<"] : ";
    cin>>a[i];
}
}

void array::print()
{
for(int i=0;i<size;i++)
{
cout<<"Data at index ["<<i<<"] = "<<a[i]<<endl;
}
}

void array::insert()
{
cout<<"Enter data to be inserted : ";
cin>>data;


for(int i=size-1;i=0;i++)
{
a[i+1]=a[i];
}
size++;                     // assigning new memory
a[index]=data;         //copying new data on last index

cout<<"Data after insertion of "<<data<<" on index["<<index<<"]"<<endl;
}

int main()   //mainfunction
{
array a;          //creating object of class

a.create();              //calling create function of class
cout<<"-------------------------------------"<<endl;

a.print();                // calling print function of class
cout<<"-------------------------------------"<<endl;

a.insert();             //calling insert function of class
cout<<"-------------------------------------"<<endl;

a.print();                   // calling print function of class

getch();
}
//Code ends
