CS684 Spring 2023

Prerequisite:

• Before starting this assignment, go through the resources provided on Reactive Kernel Resources
• Inspect and analyze the C codes, both written by hand and synthesized.

Exercise:

• Download the Assignment-1B.tar.gz file. Extract the file using command tar -xzvf Assignment-1B.tar.gz

• You will find following directory structure:

• Write reactive kernel for finding:

  1. Mean
  2. Variance
  3. Moving Average filter

1. Mean: At each step, input is a single integer x. Mean has to be found for a sequence of x’s seen so far. Following is the expected output:

• For compiling and running the program follow these steps:

cd </path/to/mean>
gcc -c mean.c
gcc -c main.c
gcc -o mean main.o mean.o
./mean

2. Variance: At each step, input is a single integer x. Mean and Variance has to be found for a sequence of x’s seen so far.

Hint: You need to remember the number of steps, mean and mean of x^2, and update it at each step. Following is the expected output:

• Variance
  

3. Moving Average: At each step, input is a single integer x. Moving average has to be found for a sequence of x’s seen so far.

Note: Your output should be exactly same as expected output including variables name as it will be autoevaluated.

Submission Instructions:

• Complete the necessary files given in the folder.
• Compress both the folders (Assignment-1A and Assignment-1B) in a .tar.gz file and provide the name as <Roll_NO>_Assignment_1.tar.gz.
• Submit it on moodle

Note: Make sure you have removed all the print statements from the file except the lines wihich prints mean and variance. Else your submission will not be evaluated.
