Algorithms Data: Stock prices input in several ways Result: mean, variance, min, max, and median of input data i begin 2 if the user enters nothing on the command line then This is the modified Project 3 greet and read the data; 4 end else if they enter one value then if it\'s a single number then Implement the mdified Project 3 logic in reading the data; end else assume the delimiter is a: count the number of entries; allocate array parse the input string and store the values into arrays 12 13 14 end end 16 else get the number of entries put each entry into an array 18 19 end 20 end 21 Now you should have the array populate 22 The same as project 3 from this point forward; Algorithm 1: Gather the data from the user then process How to run the code $./stocks .x # conditional online 2 $ ./stocks.x 13 # conditional on line 6 $ ./stocks .x 12.5,11.31 ,12,22.43 , 23.1,31 ,12,11,11.11 # conditional o /stocks . x 12.5 11.31 12 22.43 23.1 31 12 11 11.11 # conditional o

Solution

Issues found..

(1) proper header files not loaded

(2) header files .h and also include .c files also {stats.c && io.c}

(3) one extra flower brace is written which cause early closing of main function...

working code .. (only stocks.c) .. [remaining files are fine]
