The keyword inline before a function's name can make a
difference only if the function is small.
Such a thing helps in reducing the overhead of context
switching and thus making things work a little faster. It
is all upon the compiler to decide if it would really make
that inline or not. The amount of overhead depends upon the
architecture of the underlying CPU.

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.
