I need help with the following Project:
Write and test a MASM program to perform the following tasks:
- Display the program title and programmers name.
- Get the user's name, and greet the user.
- Display instructions for the user.
- Repeatedly prompt the user to enter a number.
- Validate the user input to be in [-200, -100] or [-50, -1] (inclusive).
- Notify the user of any invalid negative numbers (negative, but not in the ranges specified)
- Count and accumulate the valid user numbers until a non-negative number is entered. Detect this using the SIGN flag. (The non-negative number and any numbers not in the specified ranges are discarded.)
- Calculate the (rounded integer) average of the valid numbers and store in a variable.
- Display:
- the count of validated numbers entered NOTE: if no valid numbers were entered, display a special message and skip to (f)
- the sum of valid numbers
- the maximum (closest to 0) valid user value entered
- the minimum (farthest from 0) valid user value entered
- the average, rounded to the nearest integer
- -20.01 rounds to -20
- -20.5 rounds to -20
- -20.51 rounds to -21
- -20.99 rounds to -21
- a parting message (with the users name)
Program Requirements
- The program must be fully documented and laid out according to the CS271 Style Guide. This includes a complete header block for identification, description, etc., and a comment outline to explain each section of code.
- The main procedure must be modularized into commented logical sections (procedures are not required this time)
- The four value limits must be defined as constants.
- The user input loop should terminate depending on the value of the SIGN flag.
- The Min, Max, Count, Sum, and Average must all be stored in named variables as they are calculated
I am struggling with the average part and do not know if what I have is right or how to go about it ( I know I do not have any code to find Min or Max yet but I know how to take care of that part). Any help would be GREATLY appreciated.
Here is what I have so far:
