GoTo statements, and alternatives (help me please im new) (VB.net)
- by qais
Basically I posted a code snippet on a forum asking for help and people pointed out to me that using GoTo statements is very bad programming practise so I'm just wondering, why is it bad?
And also what alternative is there to use, like for example in this program ive done for homework the user has to input their date of birth and if the month/date/year are invalid or unrealistic(using if statements checking the integer inputs size, if theres any better way to do this i'd appreciate if you could tell me that also :D) then how would i be able to loop back to ask them again? heres a little extract of my code
retryday:
Console.WriteLine("Please enter the day you were born : ")
day = Console.ReadLine
If day > 31 Or day < 1 Then
Console.WriteLine("Please enter a valid day")
GoTo retryday
End If
