To run the malloc/realloc example from class the past few days, you can run
dynamic_array either using standard input (keyboard) or from a file.
To run using standard input:
$ ./dynamic_array
You can enter numbers, separated by whitespace. When you are done entering data,
use ctrl-d to indicate end-of-file and the program will stop reading.
To run the program with a file input, you can generate a set of random numbers
using the rand_file program. The program takes two arguments: the number of
values to generate, and the output filename:
$ ./rand_file 128 temps.txt
$ ./dynamic_array nums.txt
