please identify the fault in Q1and 2 for me

Answer 1

1. simple loop don't work.
2. case 0 dont break. if 0 make case 0-5

Answer 2

first one does not work.
second one is correct but if some one choose case 0 they will also get result from1-5 case. means two result. May be I am wrong.

Answer 3

syntactically it is correct.

edit: I don't know what you want to do with this code, so I can't comment. May be some logical error.
