6 0

Answer:

Assuming that's in python, the answer would be 4

Explanation:

The ** operator is for raising a number to a power.

The // operator returns the number of times the right number can fit into the left (i.e round division).

So the answer would be three squared over two rounded down, or 4.

Modify the countUp( ) you wrote in the previous question to countUp( num), where num is a parameter. The function displays from

algol [13]

Answer:

void countUp(int num)

{

if(num==0) //base case.

return;

countUp(num-1);//Recursive call.

cout<<num<<" "; //printing the number.

}

for input num=25

Output:-1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Explanation:

I have used recursion to print the numbers the function is in c++ language.In every recursive call we are decreasing num by 1.As the base case is reached.Then it will backtrack from 1 to num and then we are printing while backtracking.

For this lab you will do 2 things:

zepelin [54]

Answer:

Here is the Python program:

COOKIES_PER_BAG = 40 #sets constant value for bag of cookies

SERVINGS_PER_BAG = 10 #sets constant value for serving in bag

CALORIES_PER_SERVING = 300 #sets constant value servings per bag

cookies = int(input("How many cookies did you eat? ")) #prompts user to input how many cookies he or she ate

totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG)); #computes total calories consumed by user

print("Total calories consumed:",totalCalories) #displays the computed value of totalCalories consumed

Explanation:

The algorithm is:

Start
Declare constants COOKIES_PER_BAG, SERVINGS_PER_BAG and CALORIES_PER_SERVING
Set COOKIES_PER_BAG to 40
Set SERVINGS_PER_BAG to 10
Set CALORIES_PER_SERVING to 300
Input cookies
Calculate totalCalories: totalCalories ← cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG))
Display totalCalories

I will explain the program with an example:

Lets say user enters 5 as cookies he or she ate so

cookies = 5

Now total calories are computed as:

totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG));

This becomes:

totalCalories = 5 * (300/40/10)

totalCalories = 5 * (300/4)

totalCalories = 5 * 75

totalCalories = 375

The screenshot of program along with its output is attached.
