What to Hand In

• Turn in a listing of the C program you write for your project, following the required standards.
• Turn in a transcript of a session in which compile and run your program.

To compute the average of the numbers, use the calculation method of the arithmetic mean function in the NumericUtilities module (accessible from the Supplied Software page of the class website). That is, incorporate each successive number into the running average of the previous numbers.

The range of a collection numbers is bounded by the smallest and largest of the numbers.

The relative position of a number x within the range low <= x <= high is (x - low) / (high - low). Compute the range of the numbers retrieved from the keyboard by finding the largest and smallest of them.

Ground Rules

• Use aspects of C described in Lessons 1-5, 6-8, 9-13, 15, and 36 of the Winston text. This does not include arrays.
• The program must not restrict the length of sequence of numbers it retrieves from the keyboard. It should accept numbers until the person at the keyboard signals the end of the sequence (control-d on Unix - see Lesson 13 in the Winston textbook on C).
• Your program can compute the average and range of the numbers as it retrieves them from the keyboard. To compute the deviations from the average and the relative positions, the program will need to make a second pass over the data. The program can record the numbers in a file to make a second pass over the data possible.
• Define functions compute the deviation of a number from an average and the relative position of a number within a range. Put the functions in their own module and import them into the main module. Use the functions in the the appropriate part of your program.
• You may find it helpful to know that the fscanf function, besides retrieving data from a file, delivers, as its value, the number of input items retrieved.
• Read the Code of Conduct for ground rules that apply to all projects.
• The paper you submit must conform to the C Project Style Guide.
