how "%c" specification works with scanf()? -

-

i have following code 

char c; scanf("%c",&c);

now have read "%c" consume whitespaces including enter.but why when press enter (before pressing character) %c not accepting it?

so why accept enter key present in buffer due previous calls , not accept enter key before pressing character?

i assume question why inputs, including enter, not passed scanf(). not %c or %d or other type. see, special characters esc not passet io functions. recognized by, instance, console opens when executing code.
