After scanning the variable a, you will give a whitespace
character(space,tab or newline), which will also get stored into stdin file.
So next statement will scan this whitespace character.
fflush(stdin) flushes(clears) the contents of stdin file, so this time scanf
will not get whitespace character, instead it will get the character entered
by user.
or in second scanf statement, change it as scanf(" %c",&b), notice the space
before %c.
Correct me if m wrong :)
