Looking for more info on c++

I've spent a bit of time messing in c++, working on expanding my knowledge of the language now I've finished at uni. I wrote a bit of a windows program, then started a new project in two different IDEs and compiled them. The compiled programs then behaved differently.

There's evidently something else going on under the lid, but I've never encountered anything about these things in books on coding c++ and such. Is there any good tutorials or just general documentation that explains things in more depth?

dont be dumb enough to think there is a 'best' one-size-fits-all language that will automatically get you a job anywhere. Programming languages are just tools, you pick the right tool for the job

if you want to be a sys admin learn a scripting language and the shell commands in the OS you will use

if you want to be a web developer learn all the web languages

if you want to work in corperate area, learn Java or C# and a data base language

if you want to build large scale apps or do systems programming learn C, C++ and assembly
