CSCI3431 - Assignment 1 - MMMExample

Goal: A simple C program to calculate the mean and median of input numbers.

---

Intro

You have been given code that reads numbers as command line arguments and sorts them. Create a copy of sort.c named mm.c. Change mm.c to implement the following features.

• Add a function, mean(), to mm.c to calculate the mean
• Add a function, median(), to mm.c to calculate the median
• Make mm.c fork(), have the parent call mean() and child call median()
• Child should print the results of median()
• Parent should print the results of mean()
• Make the parent wait until child has finished before printing results of mean()

Each feature listed above has a corresponding issue. Please use smart commits to address each issue.

Compile

./build.sh

Usage

For example:

$ ./bin/mmm 13 18 13 14 13 16 14 21 13
Median:	14.000000
Mode:	13
Mean:	15.000000
