Description: The ‘fclose’ function is a fundamental tool in C programming and related languages, used to close a file that has been previously opened. This function ensures that all data written to the file is properly saved and releases the system resources associated with the open file. By closing a file, data loss is avoided and file corruption is prevented, which is crucial in applications handling large volumes of information. The basic syntax of ‘fclose’ is simple: a pointer to the file to be closed is passed as an argument. If the operation is successful, ‘fclose’ returns zero; otherwise, it returns a non-zero value, indicating an error. This function is part of the C standard library, making it widely accessible and used in various programming applications. Furthermore, the proper use of ‘fclose’ is considered good practice in file management, as it contributes to the stability and efficiency of applications interacting with the file system.
