CSCI3431-Assignment 1

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 immplement 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

Be sure to compile with gcc -Wall

Usage

$./sort 1 4 9 2 3 1 7 4 8
./sort: Sorted output is:
1 1 2 3 4 4 7 8 9
