Proper way to create unique_ptr that holds an allocated array

Question

What is the proper way to create an unique_ptr that holds an array that is allocated on the free store? Visual studio 2013 supports this by default, but when I use gcc versi

Answer 1

A most likely better way would be to use std::vector instead

#include 
#include 

using namespace std;

int main()
{
    vector testData(0x12, 0); // replaces your memset
    // bla    
}

The advantage is that this is much less error-prone and gives you access to all kinds of features such as easy iteration, insertion, automatic reallocation when capacity has been reached.

There is one caveat: if you are moving your data around a lot, a std::vector costs a little more because it keeps track of the size and capacity as well, rather than only the beginning of the data.

Note: your memset doesn't do anything because you call it with a zero count argument.
