For this problem, the following C library functions can be used, but no others: printf, sprintf, strcmp, atoi, sizeof, malloc, and free. Write a program that does the following:

1. Takes the following command-line arguments from the user: a secret code, a first name, a last name, and one or more whole numbers.
2. If the user doesn't give a sufficient number of command-line arguments, output "Invalid input" and terminate.
3. If the user doesn't give the correct secret code, output "Incorrect secret code" and terminate. The correct secret code is: hHFmas. (Hint: strcmp returns 0 if the two string arguments match.)
4. Store the first and last name in a string variable called fullName, with a space between the first and last name. (Hint: Use sprintf.)
5. You must use malloc to allocate sufficient memory for the fullName variable, and deallocate that memory before program termination.
6. Output fullName and the average of the numbers on the command line. The average must be accurate to 1 decimal place.
7. The program must work for names of any length and an arbitrary amount of numbers on the command line.
