The scanf (" % f % f, % f \ n "); Don't need \ n

CodePudding user response:

Remove the scanf '\ n',
Because the scanf is the standard input, belongs to the line buffer, so you need to enter the enter data to the input buffer to brush to memory, so it is must be input, and add in the scanf '\ n', then enter the carriage return to '\ n' match, cannot complete submission,

CodePudding user response:

CodePudding user response:
