sys.argv is the list of command-line arguments.
len(sys.argv) is the number of command-line arguments
2) ANSWER: TRUE

1) Write a C program that displays all the command line arguments that appear on the command line when the program is invoked. Use the file name cl.c for your c program. Test your program with cl hello goodbye and cl 1 2 3 4 5 6 7 8 and cl 2) Write a C program which displays the sum of the command line arguments. Hint: use sscanf to convert the decimal arguments (which are strings) to binary numbers that...
Hello, I need help with the function below, The language I am using is Ocaml open Printf let () = for i = 1 to Array.length Sys.argv - 1 do if i + 1 <> Array.length Sys.argv then ( if Sys.argv.(i) > Sys.argv.(i+1) then ( --> printf "%s\n" Sys.argv.(i+1); ) else printf "%s\n" Sys.argv.(i); ) else printf "%s\n" Sys.argv.(i) done;; the function is taking command arguments and print them in...
I am writing a C program that takes either command line arguments or has a file passed to it using < on the command line. My question is how do I check to see if there is a file passed using <. I think I need a way to check stdin to see if there is any data present. Thanks

Hi all, I need help to do a project based on C++ smart pointers. I have to implement the class template my_unique_ptr which is a pointer management class template. Also, it's required to implement the following public methods: a. Default constructor that initializes the object to point to nullptr. b. Constructor that takes a pointer Type * as a parameter and sets the object to point there. We say that the newly created object takes ownership of the pointed memory....
For our assignment we have to use four optional command line arguments through a makefile (which says args= ${ss} ${nn} ${mm} ${pp}). They can leave out any of those variables they want, but if there is more than one they have to be in a certain order. The command line would read something like "make run2 ss=0" or "make run2 ss=0 nn=16 mm=3 pp=src" How do I use these variables in my main method? Can I just somehow use the...
PYTHON (Triangle Inequality) Write a program triangle.py that takes three integers as command-line arguments and writes True if each one of them is less than or equal to the sum of the other two and False otherwise. Note: this computation tests whether the three numbers could be the lengths of the sides of some triangle.
Objective: Use input/output files, strings, and command line arguments. Write a program that processes a text file by removing all blank lines (including lines that only contain white spaces), all spaces/tabs before the beginning of the line, and all spaces/tabs at the end of the line. The file must be saved under a different name with all the lines numbered and a single blank line added at the end of the file. For example, if the input file is given...

After reading pages 330 - 336, write a program that takes two command line arguments which are file names. The program should read the first file line by line and write each line, in reverse order, into the second file. The program should include a "usage" method that displays the correct command line syntax if two file names are not provided. Example: if my input file says Hello, World! then my output file will contain !dlroW ,olleH Hints: Use CaesarCipher...
