inputtxt

Inputtxt is a generic, non-standard term used in computing to describe a plain text file that supplies input data to a software program. In practice, it appears in documentation, tutorials, and example projects as a stand-in for a data source that a program reads at runtime. The filename is not fixed; examples commonly refer to input.txt or inputdata.txt, and sometimes use inputtxt as the identifier itself.

Content and format: Because inputtxt is plain text, its contents are human-readable and editable. A file may contain a list of lines, key-value pairs, or simple structured records (such as CSV-like lines). There is no universal schema, and the encoding is typically UTF-8, with lines terminated by a newline character. Depending on the program, comments or metadata may be included in examples but are not part of a formal specification.

Usage: Programs read inputtxt by opening the file path and parsing its contents. In teaching materials and test suites, inputtxt serves as a deterministic input fixture to demonstrate input handling, parsing, or data processing. It may be supplied through command-line redirection (program < inputtxt) or passed to a function that reads a file object.

Considerations: When using or sharing inputtxt, avoid exposing sensitive information. Ensure consistent encoding and newline handling across platforms, and document the expected format for users who must prepare the file. If the input contains large data, consider using streaming reads rather than loading the entire file into memory.
