Deallocation of memory using pointers

Deallocation of memory using pointers:

//Dynamic array initialization by using pointers

#include<iostream>

using namespace std;

void main()

{

int a;

cout<<"Enter size of array"<<endl;

cin>>a;

int *b;

b=new int[a];       //this line will allocate the dynamic memory according to the user input

//data input in array

cout<<"enter "<<a<<" element for array"<<endl;

for(int i=0;i<a;i++)

{

cin>>*(b+i);

}

delete [] b; //this command will deallocate the memory locations and you will see garbage values in output

//data output

for(int j=0;j<a;j++)

{

cout<<b[j]<<" ";

}

cout<<endl;

}
