object - Can I use blocks to manage memory consumtion in C++?

I'm trying to gain some memory saving in a C++ program and I want to know if I can use blocks as a scope for variables (as in Perl). Let's say I have a huge object that performs some computations and gives a result, does it makes sense to do:

InputType  input;
ResultType result;

{
    // Block of code
    MyHugeObject mho;
    result = mho.superHeavyProcessing();
}

/*
   My other code ...
*/

Can I expect the object to be destroyed when exiting the block?

Yes, you can.

The destructor will be called as soon as the variable falls out of scope and it should release the heap-allocated memory.
