Assignment One

Write a C program that accepts up to 255 arguments and
displays these arguments individually, one per line.

// K & R example
int argc, **argv, **envp;
main(argc, argv, envp)
{
register char **p;

   for (p = argv; *p != 0; p++) {
     printf ("%s\n", *p);
   }
}

// C99 Syntax Compliant
 
#include <stdio.h> // Stops: warning: incompatible implicit declaration of built-in function "printf"

main(int argc, char *argv[], char *envp[]) // Stops: warning: assignment makes pointer from integer without a cast
{
    char **p;

    for (p = argv; *p ; p++)
    printf ("%s\n", *p);
}

High-light the above assignment.
Paste it into a local editor of your choice.
Write the contents to a file, (e.g., hw1, but be sure to name the source file with the ".c" extension such as hw1.c).
Compile the file with gcc. (Maybe you have ssh'd to a unix box like "Turning" or you are in the systems lab with an Ubuntu box under the account "student".
Make sure it works.
Create a header file with your name, date, and any other message.
Run the script program and name an output file like hw1.txt.
Show the header file.
Show the source file with a command like "more hw1.c"
Show the compilation process.
Show the program execution.
Terminate the script program with the ^D command
Email the file to assign@pix.cs.olemiss.edu

Possible problems with using Ubuntu:

a) Gcc does not work

   dowmload gcc with the command
   sudo apt-get install gcc
   password: (type in the password located on the whiteboard)
   Bunch of status lines...
   Hit <Enter> or Y<Enter>

b) Error messages about not finding stdio.h or crt1.o

   dowmload the C include files with the command
   sudo apt-get install build-essential
   password: (type in the password located on the whiteboard)
   Bunch of status lines...
   Hit <Enter> or Y<Enter>
