What is object-oriented programming? Webopedia definition
How does polymorphism work?
This program numbers the lines found in a text file. Write a program that reads text from a file and outputs each line preceded by a line number. Print the line number right-adjusted in a field of 3 spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (i.e., wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before processing the lines of the file. This version of the program should insert a new line after the last complete word that will fit within a 72-character line.
write a code for this. serial_number contained in the header of the file will be read , if this serial number is less than a previous serial number within a successfully processed file, or is the same as another serial number within a successfully processed file, or if the field contains anything other than 7 digits, then the file must error with the reason ‘Invalid SERIAL_NUMBER’.
