Flowchart and C code

You will write a flowchart, and C code for a program that does the following:

1. Asks a user for a number
2. Uses an "if" statement to determine if the number is greater than  one. If the number is not greater than one, you must write out an error  message.
3. If the number is greater than 1, the program calculates the square and cube of the number, and displays the output to the user.
