![]() The return is also known as the new line character. On each line are several characters (including spaces, punctuation, etc.) and we generally end the line with a return (a character within the ASCII character code set). ![]() When we create a text file we usually think of it consisting of a series of lines. Text files (also known as ASCII text files) contain character data. Text File – A file consisting of characters from the ASCII character code set. The following File Input/Output terms are explained: We need to understand how to open, read, write and close text files. Most programming languages have built-in functions or libraries to support processing files as text streams. Ĭomputer files are stored on secondary storage devices and used to maintain program data over time. In current environments, stdout is usually redirected to the monitor. Streams may be redirected to other devices and/or files. The three input/output (I/O) connections are called standard input ( stdin – keyboard), standard output ( stdout – originally a printer) and standard error ( stderr – monitor). In computer programming, standard streams are pre-connected input and output communication channels between a computer program and its environment when it begins execution. Computer files may be reopened, modified, and copied an arbitrary number of times. Some types of files can store several types of information at once.īy using computer programs, a person can open, read, change, and close a computer file. A file may be designed to store a picture, a written message, a video, a computer program, or a wide variety of other kinds of data. There are different types of computer files, designed for different purposes. Just as words can be written to paper, so can information be written to a computer file. A computer file is a computer resource for recording data discretely in a computer storage device.
