For example, if the file you are reading contains the string 'Blackbird singing in the dead of night' then the following command returns only five characters of the first field: It applies the next format specifier to that portion of the field.

For example, execute this command on the same file: They are not required. Refer to the example from the last section, where the file you are reading contains the string 'Blackbird singing in the dead of night' Seek to the beginning of the file and then reread the line, this time skipping the second, fifth, and sixth fields: Piece together the string and display it: Reading a file containing the following data, Sally Level1 The next example uses a file containing the line ' Note that the decimal point counts as a digit.
