One punched card usually represented one line of code. It was one discrete object that was easily counted. It was the visible output of the programmer, so it made sense to managers to count lines of code as a measurement of a programmer's productivity, even referring to such as "card images". Today, the most commonly used computer languages ...
Notice that this original definition of a one-liner implies immediate execution of the program without any compilation. So, in a strict sense, only source code for interpreted languages qualifies as a one-liner. But this strict understanding of a one-liner was broadened in 1985 when the IOCCC introduced the category of Best One Liner for C ...
In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
Support for code comments is defined by each programming language. The features differ by language, but there are several common attributes that apply throughout. Most languages support multi-line block (a.k.a. stream) and/or single line comments. A block comment is delimited with text that marks the start and end of comment text. It can span ...
In computer technology, a line of an IBM punched card consisted of 80 characters. Widespread computer terminals such as DEC's VT52 and VT100 mostly followed this standard, showing 80 CPL and 24 lines. This line length was carried over into the original 80×25 text mode of the IBM PC, along with its clones and successors. To this day, virtual ...
The second implementation requires only one line of code and is colloquially referred to as a "highly composed" form. Readability and hence maintainability is one advantage of highly composed forms, since they require fewer lines of code, minimizing a program's "surface area". [ 1 ]

To provide for full screen "animation" of a program, a suitable I/O device such as a video monitor is normally required that can display a reasonable section of the code (e.g. in dis-assembled machine code or source code format) and provide a pointer (e.g. <==) to the current instruction or line of source code.
