Iteration Practice Test

A game loop updates a player's score each time a coin is collected. Examine the following code snippet:

`coins <- true, false, true, true

score <- 0

index <- 0 // initialization

WHILE (index < LENGTH(coins))

{

IF (coinsindex = true)

{

 score <- score + 10     // update game state

}

index <- index + 1 // advance to next coin event

}

PRINT(score) // prints final score`

What is the output of the following loop?

A club filters a list of ages to count members who can attend an 18+ event. Examine the following code snippet:

`ages <- 16, 18, 21, 17, 19

count <- 0 // accumulator for qualifying ages

FOR (index <- 0; index < LENGTH(ages); index <- index + 1)

{

IF (agesindex >= 18)

{

 count <- count + 1      // increment when criteria met

}

}

PRINT(count) // prints number of qualifying ages`

What is the output of the following loop?
