Answer 1

Yeah, I tried that. In that case, I am getting No Output
The problem is my program is treating every character as a vowel. But I am cant realize how to solve it.

Answer 2

First you should know what is empty character constant then you can solve it.

Answer 3

x=='a'||'b' does not work - you have to write x=='a'||x=='b' etc.

Or you go for another solution, for example a switch or a loop.

(There are other issues, but first try and see if you can get it going alone from here.)
