C++ Tip: Aware of the confusion between delete with delete[]

13 Aug 2011BWake

It is a bad idea to treat built-in types differently than programmer defined classes. If you delete a dynamically allocated array of a built-in type without the brackets the memory buffer may go away just fine. This is not guaranteed. The VS2008 runtime throws an exception. There is a...

Ger Hayden

Software Developer

Ireland

My first program was written in Basic on a Sinclair Spectrum ZX 16K in the summer of '85. Having studied Computer Systems I attempted to break into the world of C but took a wrong turn and got immersed in COBOL!

I looked a C again in 1994 but didnt follow up on it. In 2001 I introduced myself to Visual C++ 6.0 courtesy of Ivor Hortons book, but found the going difficult. I tipped my toe in the .NET water in '05 but the first example I tried in VC++ 2005 express didnt work and allied with the absence of MFC in the express package, I parked that up.

Along the way my career got shunted into software testing

A personal machine change force me to migrate to VS2008 in 2008. The new edition of Ivor Hortons book for VC++ in VS2008 reintroduced me to .NET and I got curious whereupon I went out and acquired Stephen Fraser's "Pro Visual C++/CLI and
the .NET 3.5 Platform". I was hooked!

After 20 years I think I finally found my destination.

But it would take a further 8 years of exile before I was reappointed to a developer role. In that time I migrated to C# and used selenium wedriver (courtesy of Arun Motoori's Selenium By Arun) as the catalyst to finally grab the opportunity.
