How does a constant work inside a "for" loop?

Question

Swift

Good afternoon!
Swift code:

for count in 1...5 {
     let a = count
     print(a)
}

Why, in this scenario, does the constant a change its value during the loop? Or is it re-announced each time? Thanks

Answer 1

In each cycle , the constant is re-declared . When exiting the loop, it is removed from memory.
