Answer
x = 0
This will loop infinitely because the condition in 'while True' is always true.

Answer
x = 0
This will not loop infinitely because the loop will terminate once x reaches 10.
x = 0
This will not loop infinitely because the value of x is incremented, allowing the loop to terminate once x reaches 10.
y = 5
This will not loop infinitely because the for loop will execute a fixed number of times (5) and then terminate.
Step 3
Using pseudocode, write an algorithm that will use a count-controlled loop to print out the numbers 1 to 10 in ascending order.

Answer
for i = 1 to 10
print i
next
This pseudocode uses a count-controlled loop that starts at 1 and goes up to 10, printing each number in ascending order.
