The calculator we use, we can find the logarithmic operations like log base e and log base 10. So, the question arises what shall we do if we want to calculate log base 2 or log to the base any number other than log base e and log base 10. The answer is within your calculator. You just need to recall a logarithmic formula read in mathematics. The formula is :

Is drag and drop the future of programming?
Drag and drop in
programming means selecting an object from the given toolbox holding the mouse
click, moving it (dragging) on the form given in the software and then finally
placing (dropping) at the desired place on the form. This feature comes with
GUI (Graphical User Interface) based programming. A form is given to the
programmer, and a toolbox containing various...
