Violations of aliasing rules and of violating the effective type of an object are two different things and should not be confounded. Aliasing is the property of two pointers a and b that refer to the same object, that is that a == b. The effective type of a data object is used by C to de...

ParameterDetailsRETURNSSpecifies the data type that can be returned from a function.RETURNActual variable or value following the RETURN syntax is what is returned to where the function was called from. A stored routine is either a procedure or a function. A procedure is invoked using a CALL st...

Most command line tools rely on arguments passed to the program upon its execution. Instead of prompting for input, these programs expect data or specific flags (which become booleans) to be set. This allows both the user and other programs to run the Python file passing it data as it starts. This s...

A Handler can be easily used to execute code after a delayed amount of time. It is also useful for executing code repeatedly after a specified amount of time by calling the Handler.postDelayed() method again from within the Runnable's run() method.
