Re: [Dev-C++] scanf with gets

[Ricardo R. <ri...@un...>]

scanf ( ) doesnot read the 'return' char,
then it stays in the input buffer until the next reading.
Two options for the next sentence:
(1) If you read in the next sentence with gets( )
the 'return' char is transformed in the
empty char string:  " " = '\0' .
(2) If you read a char in the next sentence with scanf( )
the 'return' char it is transformed in the 'line jump'='\n'.

In consequence, if you dont want any strange/side effect in your input
the best option I know after an entry with scanf( ) it's to free the 
input buffer:

             fflush(stdin).


Any other explanation is wellcome,
but I hope it can help you,
Ricardo.
