and

Required
Determine the output of the code
if cost < 70 or cost > 150
The above condition checks if cost is less than 70 or cost is greater than 150
This condition is false because 100 is neither less than 70 nor is it greater than 150

Which means
discount = 100
So, the print instruction will print: Your cost is 100
Answer:
Place holder
Explanation:
In computer programming, placeholder is a word, character or series of characters that is used to take up the space until the time when the space is actually needed. It is widely used in the sign up or login forms for web and mobile applications. For example, First Name, Last Name etc.
A programmer might have an idea that he will require this number of characters or values but he don't knows what the input will be, that’s why he uses the place holder.
Hope it helps!
