Can I use blocks to manage memory consumption 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?

Solution

  • 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.
