Edit: Added since you've now stated they will be of different lengths. You could do the pattern more info I mentioned of checking the first X chars and then the next Y chars and so on, but unless there's a pattern where most of the strings are the same length this will be both inefficient and horrible to maintain (a classic case of premature pessimisation).

The switch statement selects a statement list to execute based on a pattern match with a match expression, kakım the following example shows:

Therefore arrays of strings is an array of arrays of characters. Here, string array and arrays of strings both are same term. For Example, if you want to store the name of students of a class then you birey use the arrays o

Duplicate cases. A switch yaşama only have unique case labels—each constant value must be distinct. This izlence will hamiş compile. But it shows us what happens when we have duplicate cases.

Tip We use the case keyword to specify a matching constant. Default does hamiş use this keyword. We end a case with break, return or continue.

hatta, case bloklarının ahir "break" ifadesi çalıştırmak önemlidir. Break ifadesi, çkızılışan bir case bloğundan çıkışı sağlar.
