Reading and Writing Files in C

1. Read the current source file
   Implement a small C program consisting of a single source file readme.c. The program must print its own source code to stdout. To do so, use the functions fopen(.) and fgetc(.). You can implement this directly in main(.).
   Name the source file: readme.c
2. Extended ASCII Codes
   Implement a C program that reads its own source code and prints each character's ascii code on a separate line. Note: you don't need a separate function to obtain a char's ascii code.
   Name the source file: ascii.c
3. Number of Lines
   Implement a C program that prints the number of lines of a given file to stdout.
   Name the source file: line_count.c
