Your program will: Read in that data file into a 2 dimensional array, 6 rows by 4 columns. Each row represents a Factory with 4 shifts. The integer value represents the number of units produced at each shift for that Factory. 2 Allow the user to do several different tasks: Display the current Factories and each of their shifts' production runs (e each Factory 1 to 6 will each have 4 shifts Calculate the Highest and Lowest production runs among all of the shifts (total of 24 different shifts, 6 different factories X4 shifts each Calculate the Average production nun among all of the shifts (total of 24 different shifts, 6 different factories X4 shifts each) PLUS the average production run PER each Factory among its own 4 shifts Allow the user to manually change the production nun value for a particular factory for one of its 4 shifts (e,g. Factory 3, Shift #4) QUIT 3- se functions to carry out each task. The main is reduced to a switch that calls out one function We are passing an array to the function. We know there is a maximum of 24 values 6 factories with 4 different shifts each). You may want to use a nested for loop since that would be the easiest approach The average for each individual factory would be an "interesting calculation since we would have to know when to stop and when to start a factory within that nested for loop The first index location is always zero but humans are not use to seeing "Factory #0". How would display it as "Factory #1" instead (and No. let's use all elements of the array and not ignore the "zero" row and "zero" columns If we change any existing value for a factory shift's production run, we have to check for 1. Valid Factory value (e.g. 1 to 6) 2. Valid Shift value (eg 1 to 4) 3. No negative integers for the production run (zero is legitimate as avalue)
