Line Numbers and Syntax Errors
If a programmer introduces a syntax error into a program, the compiler (or interpreter) will inform the programmer that the attempt to compile (or execute) failed at the given line number. This simplifies the job of finding the error immensely for the programmer.
The use of line numbers to describe the location of errors remains standard in modern programming tools, even though line numbers are never required to be manually specified. It is a simple matter for a program to count the newlines in a source file and display an automatically generated line number as the location of the error. In IDEs such as Microsoft Visual Studio or Xcode, in which the compiler is usually integrated with the text editor, the programmer can even double-click on an error and be taken directly to the line containing that error.

Famous quotes containing the words line, numbers and/or errors:
“Next to the originator of a good sentence is the first quoter of it. Many will read the book before one thinks of quoting a passage. As soon as he has done this, that line will be quoted east and west.”
—Ralph Waldo Emerson (1803–1882)
“Green grow the rushes-O
What is your one-O?”
—Unknown. Carol of the Numbers (l. 2–3)
“When people put their ballots in the boxes, they are, by that act, inoculated against the feeling that the government is not theirs. They then accept, in some measure, that its errors are their errors, its aberrations their aberrations, that any revolt will be against them. It’s a remarkably shrewed and rather conservative arrangement when one thinks of it.”
—John Kenneth Galbraith (b. 1908)
