C Programmming C Programming practice gnWrite a C program that takes a command line argument of a number that you need to calculate thefactorial value of. The program must use a recursive function to calculate the result and then printthe result to standard output. The program must perform the following functionality:1. Create and save a new C program called factorial.c2. Correct type definition for recursive function.3. Correct type definition for main function to process input arguments.4. Correct type definitions for variables.5. Ensure command line arguments to read in the input number to calculate the factorial is used.6. Test if the correct number of input arguments are entered when the program is called and printan error message if insufficient arguments are entered.7. Convert the string to a number and test the entered number is not a negative number and printan error message if negative.8. Convert the entered argument to the correct data type format and call a recursive function calledto recursively calculate the factorial of the number. Ensure you use the correct data types.9. Exit the recursive function and print the result in the main calling function
