CS 320: Lab (C) Spring 2019 2. (4 points) Students shall create a program in C which reads ASCII strings from the standard input until it reaches the EOF symbol. From the accumulated input, the program shall extract only its unique tokens, seperated by the space character, and send these to the standard output. For example, if provided with a file containing a text document, it shall send to the standard output every unique word contained therein. The order the words appear in the output does not need to be sorted in any particular order. The program shall insert a space character between each output word and ignore line endings rogram INane:unique Command Line Args: |none Program Input: stdin Program Output:stdout Return 0 on completion Allowed Imports:stdio.h Example Use userQcomputer: $ ./unique
