hello...
Im new here n i hav question dat i am unable to complete...Plzz help me...

these r my codes but its not really correct...im confused how to create switches in it....Can u plz help me with it?...

I moved your question to its own thread; it is considered rude to hijack someone else's thread. I also fixed your [code] ... [/code] tags. One more bit of advice: write proper English, e.g. 'please' is not written 'plz'.

kind regards,

@sweetipie
scanf will only change the value of ch if it finds that your input character stream is consistent with the format string. If you type 'A' rather than '5' then ch retains its previous value, which will cause you to repeat the action associated with the last time through the loop.

@sweetipie
It would be a lot easier for potential helpers if you explained why this code is not satisfactory.

Are you getting compiler errors? If so, then cut and paste them into your post.

Is the program malfunctioning? If so, describe the erroneous behavior.

Do you want to refactor the program ... perhaps replace the if/elseif/else cascade with a switch statement? If so, describe your desires and constraints.
