Write a program that asks the user to enter an integer between 1 and 15. If the number entered is outside that range, your program should print out an error message and re-prompt for another number. (This is an input validation loop.) Note that the basic input statement in C is scanf (). See Unit 1 Slide 83+ for a description of that function. Once the user enters a number in the correct range, your program will print out four patterns of asterisks that look like the following. Note that the number provided by the user is equal to the height of the pattern. Let's say the input value was 8. Then the output should be: For the final pattern, ask the user for an odd number between 1 and 15(Your program should use an input validation loop to restrict valid input from the user to odd numbers between 1 and 15.) If that number is 7, then the diagram appears as follows: Note that, in contrast to the previous diagrams, there are spaces between adjacent asterisks on the first and last lines
