this is programming in C

(4 points) This program randomly combines words contained in its input stream and sends them to the output stream. At program execution, the application shall read in the entire set of words to use during the combination process. After reaching the EOF symbol, the program shall then begin randomly selecting words and combining them into a concatnated output word. By default, the program produces only one combined output word for each execution, but users behavior by providing an optional command line argument(through argy) The words the program selects must meet minimum length criteria, and users may also change this value at program execution to meet their needs. The program must accept this. By default, the program squeezes the words together and omits any spacing between them (e.g., somewhatlikethisbutrandom), but users may override this behavior with a command line argument as well, and the program will produce output with the user specified parameter. The command line arguments may appear in any order When unable to construct strings meeting the minimum length from the input stream, the program shall alert the user to an error and suggest corrective action. There shall be no duplicate words in any single output combination, but the same word may appear twice in the total output when producing more than one string (i.e. -n specified >1) Program Name: crunch Command Line Args:-d Number of words from input stream to combine in each crunched output (default -4) -m The minimum length of each word used (default -6) -n Number of output strings to produce (default -1) -s Indicates to insert a space between the output words (default-none) Program Input: stdin Program Output: stdout Return 0 on completion Allowed Imports: stdio.h stdlib.h time.h Example Use: userecomputer: s ./crunch 1) Program Name: crunch Command Line Args:-d Number of words from input stream to combine in each crunched output (default -4) -m The minimum length of each word used (default -6) -n Number of output strings to produce (default -1) -s Indicates to insert a space between the output words (default-none) Program Input: stdin Program Output: stdout Return 0 on completion Allowed Imports: stdio.h stdlib.h time.h Example Use: userecomputer: s ./crunch
