How do you make record file in c language?

To create a record file in C, you typically define a structure to represent the record data, then use file handling functions to write to a file. First, include the necessary headers like <stdio.h> and define your structure. Use fopen() to open a file in write mode, and then use fwrite() or fprintf() to write the structure data to the file. Finally, close the file with fclose() to ensure all data is saved properly.
