the second is matched to the second specifier and placed in the second column and so forth If there are more words than specifiers then the process is repeated until all words have been processed or the limit imposed by any(non-whitespace) text in the format that is not one of these specifiers is considered a literal. If there is a literal between two format specifiers then that same literal must appear in the input stream between the matching words. The following specifiers are valid
nd example oindent opens the file binary numeric values will be read assuming they are stored in IEEE format with the least significant bit and then converted to the native representation Opening a file that is already open simply opens it again and returns a separate file id It is not an error to open a file several though writing to the same file through several different file ids may produce unexpected results The possible values of text mode reading and writing automatically converts linefeeds to the appropriate line end character for the you may append a you must also open the file in binary mode The parameter conversions are currently only supported for and permissions will be set to and then everything is written in a single operation This is very efficient and improves performance c
