Iteration Practice Test

A student generates a numeric pattern for a display by iterating a fixed number of steps. Examine the following code snippet:

`result <- ""

FOR (i <- 1; i <= 4; i <- i + 1) // initialization, condition, update

{

result <- result + (i * 2) + " " // append even number and a space

}

PRINT(result) // prints the built sequence`

What is the output of the following loop?

A student searches a list of usernames to find the first match. Examine the following code snippet:

`names <- "Ava", "Mia", "Noah", "Liam"

target <- "Noah"

index <- 0 // initialization

foundIndex <- -1

WHILE (index < LENGTH(names))

{

IF (namesindex = target)

{

 foundIndex <- index     // store where it was found

 index <- LENGTH(names)  // force termination

}

index <- index + 1 // advance each iteration

}

PRINT(foundIndex) // prints index or -1`

What condition causes the loop to terminate?
