A free-format language ignores whitespace characters: spaces, tabs and new lines so the programmer is free to style the code in different ways without affecting the meaning of the code. Generally, the programmer uses style that is considered to enhance readability. The two code snippets below are the same logically, but differ in whitespace.
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.
Coding conventions allow programmers to have simple scripts or programs whose job is to process source code for some purpose other than compiling it into an executable. It is common practice to count the software size (Source lines of code) to track current project progress or establish a baseline for future project estimates.
The authors explain the birth of the one-liner paradigm with their daily work on early Unix machines: The 1977 version had only a few built-in variables and predefined functions. It was designed for writing short programs […] Our model was that an invocation would be one or two lines long, typed in and used immediately.
4 physical lines of code (LOC): is placing braces work to be estimated? 2 logical lines of code (LLOC): what about all the work writing non-statement lines? 1 comment line: tools must account for all code and comments regardless of comment placement. Even the "logical" and "physical" SLOC values can have a large number of varying definitions.
The class is one of the many available to students in the lower security of DC’s two jail facilities. Administrators and detainees alike are grateful for the opportunities. The students make ...
In computer programming, indentation describes formatting source code with whitespace to the left of code text – often to visually show that a sequence of code lines is syntactically a code block. Typically, the lines of a block are aligned with an amount of white space that indicates the block's depth in the hierarchical structure of the ...
Why is that ambiguous? Because it has more than one semicolon? -from a non-programmer I would say one line of code. When counting lines in a large program it is usually done mechanically (i.e. by a program), so it isn't going to think it the way a person would. If it were reformatted it would count as two lines. That is why SLOC is a rough ...
