Static, Stack, Heap Array and time

[26friends26]

hi..i need help with this one:

write three functions in C/C++; one that declares a large
array statically, one that declares the same large array on
the stack, and one that creates the same large array from
the heap. Call each of the subprograms a large number of
times (at least 100,000) and output the time required by
each.

so i know that heapArray uses the word new..

void StaticArray()
{
     int x[1];
}


void HeapArray()
{
     int *z;
     z = new int[1];
}

is my static and heap function are correct?.
and please help me for the stack array function.
and how am i going to calculate da strt time and end
time for each if i put a for loop that will call each function.?

thanks.

In the first function you have an array on the stack, not a static array.
In the second function you have a memory leak. You must delete[] whatever is allocated with new[].

It is foolhardy to time something that has no net effect and thus could be optimised away by the compiler. Surely your teacher is expecting these functions to actually do something.

oh yeah ur right.
the first function is really stack array.
and to make it static, i should put "static"
on the declaration, right?

ex.. static int x[50]; ???

Yes, that is correct.
