Formatted output to Command-Line contd. ,[object Object],specifies the platform line separator so “%n” will have the same effect as “”. n specifies that the argument is a boolean value, so it will be output as “true” or “false”. B specifies that the argument is a string. S specifies that the argument value is a character and should be displayed as such. C apply to floating-point values and specify that the output representation should be decimal notation, scientific notation (with an exponent), or hexadecimal with an exponent, respectively. f, g, and a Apply to integers and specify the no. system to be used to output the integers. d, o, and x Meaning Conversion Character
