Create a C program that validates a CSV file based on a header line at the top of the file. The header line will represent the attribute names and the number of attributes. For example, if the header line is `ID,NAME,PRICE,QUANTITY`, you know that there are 4 attributes. All subsequent lines of data must include 4 attributes to be considered valid. **Requirements** - Prompt the user to enter a file name. - Check your file pointer to make sure the file exists. - If the file passes validation, print the name of the file and a message indicating that it is valid. - If the file does not pass validation, print each line that is not valid. - The validation code should be implemented as a separate function. - Include a corresponding header file that contains any `#include` statements, `#define` statements, and function **declarations**. - Save your code as `csv_check.c` and `csv_check.h`.
