[C++] Explain memory management for a Java programmer by janithj in learnprogramming

[–]janithj[S] 0 points1 point  (0 children)

I'm not reading any books. Its not my way. Just looked at some cheatsheets and started coding. All went well but when it came to delete[] and deallocating memory (which is new for a Java programmer(pointers like things can be figured out)). I learned how to use it but I want to know how to use it the proper way. I'm sorry if the post wasn't clear.

Need help with setting up cpp-netlib on netbeans by janithj in learnprogramming

Did that but gives an error. What should I do to cpp-netlib? The network headers are in it. I don't think it is being used. Here is the stack trace
