Writing to a file

Writing to a file: C: Data Structures, Pointers, and File Systems
Writing to a file: C: Data Structures, Pointers, and File Systems

To create a file for writing or append to an existing file, use the fopen() function with the mode options "w" or "a", respectively. A file opened for writing is created if it doesn't exist or, if it does exist, it's overwritten. File writing functions resemble the standard output functions in C, but with an extra argument for the file handle. Ensure that you close a file opened for writing so that the last bit of data is sent to the file.
