with the use of new operator i have to allocate memory of integer array of 10 elements in constructor and similarly deallocate it in destructor.

please help me out

Please read memory allocation fundamentals from some c++ book or from cplusplus.com or related c++ site. Also read constructor destructor. Follow posting guidelines of TSDN.

i know the concept of concept of constructor and destructor
as we use for loop
in constructor

 
for (i=0;i<10;i++) &a[i]=new(int); //some thing like that i am not sure whether it is correct or not
 
 

in destructor how to dealloacte this memory
please help me out

In destructor,

for (i=0;i<10;i++)  delete a[i];

Actally, you would allocate it like this if you just want an array of integers.:

int *myArray = new int[10];
 

To deallocate:

delete[] myArray;
 

If you want an array of pointers to integers allocated on the heap, then that is different. Something like:

int *myParray[10];
for (int x = 0; x < 10; x++)
    myParray[x] = new int;
// ... to deallocate ...
for (int x = 0; x < 10; x++)
    delete myParray[x];
