What is the number of stars displayed by the following lines of instruction ?

n <- 5
For i <- 1 to n Do
    For j <- n to i [-1] Do
        Write("* ")
    End For

End For

Consider the following sequence of instructions. Assume that the user has typed the values 0, 2, 4, 30, 12, 18, 24 in order. What is the last value read?

i <- 1
val <- 0
Do
    Read(val)
    i <- i + 6
While (val % 6 != 0)

Which conditions allow the write instruction to be executed?

Do
    Read(val)
While (val < 0 OR val >= 10)
Write(val)

Analyze the sequence of instructions below. Then, choose which of the following statements are true. Assume that each variable has been correctly declared.

n <- 5
arr <- {1, 2, 3, 4, 5}
tmp <- arr[1]
For i <- 1 to n Do
    arr[i - 1] <- arr[i]
End For
arr[n] <- tmp

In the following sequence of instructions, how many times is the string "hello" displayed?

For i <- 1 to 10 [2] Do
   Write("hello\NL")
End For

What is the value of the variable count at the end of execution of the following sequence of instructions ?

count <- 0
For i <- 2 to 5 Do
    For j <- 1 to 2 Do
        If i % j = 0 Then
            count <- count + 1
        End If
    End For
End For
