Pencil Code was created by David Bau and his son in 2013. It was inspired by Logo , the 1967 programming language for drawing on a screen using a Lisp -like programming language. [ 4 ] Google has funded improvements to Pencil Code via Google Summer of Code projects.
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...
The Pencil Code has mainly been applied to describe compressible turbulence and resistive magnetohydrodynamics. Applications include studies of planet formation , [ 2 ] the solar dynamo , [ 3 ] mono-chromatic radiative transfer , [ 4 ] the coronal heating problem , [ 5 ] debris disks , [ 6 ] turbulent combustion of solid fuels, and others.
However, the compiler automatically transforms the code so that the list will "silently" receive objects, while the source code only mentions primitive values. For example, the programmer can now write list. add (3) and think as if the int 3 were added to the list; but, the compiler will have actually transformed the line into list. add (new ...
byte, short, int, long, char (integer types with a variety of ranges) float and double, floating-point numbers with single and double precisions; boolean, a Boolean type with logical values true and false; returnAddress, a value referring to an executable memory address. This is not accessible from the Java programming language and is usually ...
Real Programmers Don't Use Pascal" [1] (a parody of the bestselling 1982 tongue-in-cheek book on stereotypes about masculinity Real Men Don't Eat Quiche) is an essay about computer programming written by Ed Post of Tektronix, Inc., [2] and published in July 1983 as a reader's contribution in Datamation.
Splint's output: Variable c used before definition Suspected infinite loop. No value used in loop test (c) is modified by test or loop body. Assignment of int to char: c = getchar() Test expression for if is assignment expression: c = 'x' Test expression for if not boolean, type char: c = 'x' Fall through case (no preceding break)
find_character(string,char) returns integer Description Returns the position of the start of the first occurrence of the character char in string. If the character is not found most of these routines return an invalid index value – -1 where indexes are 0-based, 0 where they are 1-based – or some value to be interpreted as Boolean FALSE.
