student marks program

Hi,

for example:

In X board if you fail in 1 subject, the final result will show as fail only. Even if you score above 90.

I want a logic for code which should show as fail in the result section even if 1 subject score is less than 35 .

In my code it is showing as first class even if I put 34 in one of the subject.

Please let me know what logic should be applied.

Thanks,
Anurag

Try the code I have pasted . Key is to check for all the marks if less than 35, set option to 5.
