I'm using monodevelop IDE in ubuntu 14.01
but this compiler doesn't help me!!
when I write double .. I have to write it completely ... there is no list appear when I write dou
what is the keyboard short cut to make that list appears???
Monodevelop does not have code-completion for C++, at all. The IDE has support for C++ in so far as it can syntax-highlight, fold-code, manage project files and call the compiler but that's pretty much it.
If you want a richer C++ development experience on Linux try Code::Blocks, CodeLite, Eclipse, Netbeans, Anjuta, KDevelop or QtCreator.
Does not compute. The current stable release is 12.04, and development has only really started for 12.10. In Ubuntu version numbers, the left of the dot is the year of release and the right of the dot is the month. Ubuntu releases in April and October, and not January, so a .01 release is impossible (this is why you only ever see .04/.10 releases). And last I checked, it's only 2012...so a 14 release is also impossible...
I write tens of thousands of lines of code without an IDE. A good IDE can improve your productivity. Some people's productivity is not significantly improved by them. Some people use other tools to achieve much the same ends (and, as in my case, my productivity would drop if I had to switch to an IDE).
