Simple console mode menu handling

[vedro-compota]

mmmm....i need clean input before getting the menu command so the code'll be =

Code Select Expand

while (getchar() != '\n');
printf("\n%s",mtext );
   ch = getchar();

You can do that... or you can do this...

Code Select Expand


printf("\n%s",mtext);
scanf(" %c", &ch);


Note the leading space between the " and % in the scanf() ... that tells it to ignore invisible characters (Enter, Tab, spaces, etc) hanging around in the buffer.

hm. the while (getchar() != '\n'); will stop program if the buffer is empty scanf() can get visible symbol from previous line which was put into input and hadn't been read at the whole - is there any way to check - is the buffer empty before call something which can make it so = http://forum.pellesc.de/index.php?topic=4052.0

That is the current standard for C programming.

Could be. Saw this happen in the tinyPDF thread to me yesterday, but all links that I tried today, just now, are working fine....
