Dynamic allocation in C++

[radhikutti]

Hi All,

As per my knowledge, We can use new operator for dynamic memory allocation and free function can be used to deallocate the allocated memory.

Free function behaves similar to Delete function in C++.

Please let me know information about this.

Thanks in Advance

If you used new then you should release the allocated memory using delete.

You should only use free to release the allocated memory if you allocated it using malloc or calloc.

Hellow,
Your information is correct.

new operator is used to allocate memory space at run time, and delete operator is used to free memory space at run time(Allocated memory).

In c++,

new operator is used inside constructor, to allocate memory space for member data or data members.
delete operator is used inside destructor, to free memory space for member data or data members (Allocated memory).

new operator is same as malloc, calloc in C.
delete operator is same as free in C.

Bye...

Hi,

Is it must that we have to use delete function to release memory allocated with new operator.

Hi,

Yes Sure, Then only memory releases. In C++, no Garbage Collection Facility. Java only have Garbage Collection facility. It means automatically memory releases at the time of program end.
