These flashcards cover key vocabulary and concepts related to input and output operations in C programming, as discussed in the lecture.

Stream

Any source of input or destination for output in C programming.

Standard Input (stdin)

The stream from which input is read, usually the keyboard.

Binary File

A file where bytes do not necessarily represent characters and have a defined format.

fopen

A function used to open a file and returns a pointer to a FILE structure.

fclose

A function that closes an opened file.

Buffering

Storing data in a memory area to enhance the performance of I/O operations.

FFlush

A function that flushes the output buffer for a stream.

fscanf

A function that reads formatted input from a specified stream.

fprintf

A function that writes formatted output to a specified stream.

getc

A function that reads a character from a specified stream.

fgets

A function that reads a line from a specified stream into a string.

sscanf

A function that reads formatted input from a string.

ftell

A function that returns the current file position of a stream.

fseek

A function that sets the position of the next read or write operation on a stream.

remove

A function that deletes a file.

rename

A function that changes the name of a specified file.

tmpfile

A function that creates a temporary file.

tmpnam

A function that generates a name for a temporary file.

EOF

End of file indicator, a negative integer value.

ferror

A function that checks if a read/write error has occurred on a stream.

feof

A function that checks if the end of the file has been reached.

Mode String

A string specifying the operations for opening a file, such as 'r', 'w', or 'a'.

File Pointer

A pointer indicating the file structure used to access a file.

Structure variable

Used to hold data that includes multiple variables.
