divide each row into smaller elements.These are delims and tokens.Delims is used to tell each line for what should be used as a separator. The default Delimiter is space and tab key.For example, if the above file is used, we can execute the following command:For/f "delims =" % I in (a.txt) do echo % IThe result is as follows:1st rows and 1st Columns2nd rows and 1st Columns3rd rows and 1st ColumnsWhy. The delims parameter = is followed by a space, which means that each element is separated by a

The token is then sent to the client's form form, using a hidden field in the form form to store the to

, standard C allows for whitespace on either side, but older compilers may not allow this. If a row contains only # (and whitespace), then the line in standard C is interpreted as blank. The entire preprocessing statement can be followed by only whitespace characters or annotations, and no other content.2, name represents the macro name, which can take parameters. The parameter can be a variable argument list (C99).3, you can use "\" in the statement to wrap the line.e.g.# define one 1/* one = 1
