I been a buzztouch member for some time now and if i may say, must of us here do not know how to code. so i need an urgent help with this simple c++ code. Write three functions in C or 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. Explain the results. Help please and thank you in advance.

haha! Stackoverflow is the homework answer source! http://stackoverflow.com/questions/7996085/what-is-the-difference-in-execution-time-for-allocating-to-the-heap-vs-the-stack

I have seen these online. it comes up with an error, when i run it in xcode.

could be that iOS uses objective-c, not C++. What is it you're trying to achieve?

basically to write the code that would generate the output as it is asked in the question.

well, if this is just to answer a homework question that's written exactly like you have it, then someone else will probably have to answer it - I don't know C++ as well as objective-c, sorry. :(

if you can answer the question in Objective -c, that would be great too. The chooses are to write it in c or c++. Thank you

objective-c is different than "c" or "c++". Think of c/c++ as the underlying framework over which objective-c is built. Hence, your question is dealing with things such as clock management that is probably beyond the scope of objective-c.

i see.
