Second scanf is not working

Question

i am having trouble with this c language code:

 char st[2];

 printf(\"enter first value:\");
 scanf(\"%c\", &st[0]);

 printf(\"enter second value:\");
         


        

Answer 1

use fflush(stdin); function before the second scanf();. It will flush the ENTER key generated after first scanf();. Actually, your second scanf() is taking the ENTER as its input and since scanf terminates after getting an ENTER, it is not taking anything else by your side.
