1.)
<span>((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) </span>
<span>The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. </span>
<span>For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. </span>
<span>a.) (i <= n) || (i >= n) </span>
<span>This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. </span>
<span>b.) (a[i] == 0) && (a[i-1] == 0) </span>
<span>This means that both of these terms are true. We substitute. </span>
<span>((i <= n) && true) || (((i >= n) && true)) </span>
<span>Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: </span>
<span>(i <= n) || (i >= n) </span>
<span>This is clearly always true. </span>
Answer:
yes i agree with that the answer is in fact true
Explanation:
follow my in sta gram at grac.ehihi
Answer:
The program in Python is as follows:
qty = int(input("Quantity: "))
price = 100 * qty
if qty >1000:
price = (100 - 0.10 * 100) * qty
print("Cost: "+str(price))
Explanation:
This prompts the user for the quantity
qty = int(input("Quantity: "))
This calculates the price or cost, without discount
price = 100 * qty
This checks if the quantity is greater than 1000
if qty >1000:
If yes, this calculates the price or cost, after discount
price = (100 - 0.10 * 100) * qty
This prints the calculated cost
print("Cost: "+str(price))
