Mida tähendab võtmesõna 'inout' kasutamine programmeerimises ja kuidas see mõjutab andmete edastamist funktsioonides?

In programming (for example, in Swift), the keyword inout indicates a function parameter that is passed by reference and can be modified inside the function, with changes visible outside.

This means that when calling a function with an inout parameter, you are passing a reference to the original variable, not a copy of its value. Inside the function, you can change the value of the parameter, and after the function exits, the variable will have the new value.

Example in Swift:

func increment(value: inout Int) {
    value += 1
}

var number = 5
increment(value: &number)
print(number) // Will print 6

Here, number changed because value was an inout parameter.
