How to check command line arguments in any order

Here is an easy solution to passing parameters to a C++ application from the command line that does not require any external libraries. Since parameters are read inside a loop, the order in which they are passed is not important. #include <string> #include <iostream> int main(int argc, char* argv[]) { for (int i = 1; i < argc; i++) { std::string s(argv[i]); if (s == "-a") { std::cout << "You passed parameter -a" << std::endl; } else if (s == "-b") { std::cout << "You passed parameter -b" << std::endl; } else { std::cout << "Unknown: " << s << std::endl; } } return 0; }

Solution: Netbeans 8 not working on Ubuntu 15.10

Netbeans is one of my beloved day to day applications. Yesterday, when I installed Ubuntu 15.10 (Wily Werewolf) on my computer, Netbeans started to hang on the startup screen, specifically at the Loading Modules phase. It took me hours looking for solutions on the internet; and reinstalling different versions of the Java Development Framework didn’t seem to help. Finally I found the following fix at an Ubuntu forum, which turned out to be very simple to apply.

Compiling and Debugging Oracle's Pro*C files in OS-X / Xcode

Part of my work as a Web/UNIX developer includes maintenance and development of tools using Oracle’s Pro*C. In text interfaces, VIM is a pretty decent tool for creating source code and their companion make files. If you created the right make file, compiling is also a breeze. However things get kind of tricky when you have to debug. Oh my! This can be a difficult task. Many may say that there’s nothing like gdb, but come on guys, even you can’t deny the beauty of a visual debugger.

How to redirect stdout / stderr to a file

Redirecting all your program output to a file is very simple and can be accomplished like this: myapp > output.log This line will send all the output generated by myapp to a file named output.log. The contents of output.log will always be overwritten; but you can use a second > to append to the current content like this: myapp >> output.log As well as with output, it is very useful to redirect the stderr (standard error output) to a file rather than to the screen.
