C Programming What does the below do? Where is the output going? Where is the input coming from? #include #define RECORD_LENGTH 60   void main(void) { FILE *fptr; char stock_price_shares[RECORD_LENGTH + 1];   if ((fptr = fopen("PORTFOLIO.DAT", "r")) == NULL) printf("\nCannot open the file: PORTFOLIO.DAT\n"); else { while ( fgets(stock_price_shares, RECORD_LENGTH + 1, fptr) != NULL ) fprintf(stdout, "\n%s", stock_price_shares); fclose(fptr); //close the file } }

Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line. Be sure to test whether a file open succeeds or not and close any file you open when done.

Define the following data structures: Record   File   Array     String

Python 3  Given that a variable named pathName contains a string describing a directory path, write a single Python statement that will store the names of all files and subdirectories in that path in a List structure named contents. DO NOT traverse the path/directory. You are only interested in the immediate path and its contents. You may assume that any necessary import statements already exist.
