C++ smart pointers including auto_ptr and shared_ptr

Note this is not complete!!

Smart pointers are used to prevent dangling pointers.
This is a demo of an auto_ptr:
using namespace std;

class MyClass {
MyClass() {} // nothing
~MyClass() {} // nothing
void myFunc() {} // nothing

int main() {
auto_ptr ptr1(new MyClass), ptr2;

ptr2 = ptr1;

MyClass* ptr = ptr2.get();


return 0;
Auto_ptr has ownership but when you assign to another auto pointer, the assign auto pointer will lose ownership. The right hand side can also get modified.
Need to complete both types including shared_ptr within Boost. Need to know pros and cons of each.

NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!

About caustic

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at youtube.com/quantlabs
