[Tutor] A problem involving exception handling, need suggestions to improve further

[Manprit Singh]

Dear sir ,

In the below written mail , we are only raising an exception . I need to
make a program that can end normally while displaying a message "Wrong
value of order entered"  without error  if a user provides inappropriate
input  in a function call like ser_gen(9, -1).

Regards
Manprit Singh
