I assume your friend thinks youâre batty because of your beverage opinions and not for other reasons beyond my expertise. Given that, Iâd have to side with your Perrier-drinking pal, but also assure you that it is a common misconception that carbonation pulls calcium from your bones.
Functions [edit]. A function, which can also be referred to as subroutine, procedure, subprogram or even method, carries out tasks defined by a sequence of statements called a statement block that need only be written once and called by a program as many times as needed to carry out the same task.
A program is free software if the program's users have the four essential freedoms: 1  The freedom to run the program as you wish, for any purpose (freedom 0). 2  The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
