Some languages have special semantics for obtaining a known line number from a file.
|
|
|
|
|
|
;Task:
|
|
Demonstrate how to obtain the contents of a specific line within a file.
|
|
|
|
For the purpose of this task demonstrate how the contents of the seventh line of a file can be obtained, and store it in a variable or in memory (for potential future use within the program if the code were to become embedded).
|
|
|
|
If the file does not contain seven lines, or the seventh line is empty, or too big to be retrieved, output an appropriate message.
|
|
|
|
If no special semantics are available for obtaining the required line, it is permissible to read line by line.
|
|
|
|
Note that empty lines are considered and should still be counted.
|
|
|
|
Also note that for functional languages or languages without variables or storage, it is permissible to output the extracted data to standard output.
