nAssume that k is declared as an Integer. The loop should iterate until -1 is input.

 Do While k <> -1

 InputBox(“Enter a number -1 to quit:”, VB6)

 Loop

Assume that z has been initialized to 50. The values from 0 to 50 should be totaled.

 While (z>=0)

 sum = sum + z

Identify and correct the error(s) in the following (you may simply need to add code):

Assume that y and total are declared as Integers

total = 0

Do Until y = -1

Print y

y = InputBox(“Enter a value, value input”)

total = total + y

Loop
