Entry controlled loop - <u>The loop which has a condition check at the entrance of the loop, the loop executes only and only if the condition is satisfied is called as entry control loop.</u>
So, for and while loops are its examples.
Answer:
The solution code is written in Python 3
- total = 0
- count = 0
- neg = 0
- pos = 0
-
- num = int(input("Enter an integer: "))
-
- while(num != 0):
- total += num
- count += 1
-
- if(num < 0):
- neg += 1
- else:
- pos += 1
-
- num = int(input("Enter an integer: "))
-
-
- print("The number of positives: " + str(pos))
- print("The number of negatives: " + str(neg))
- print("The total is " + str(total))
- print("The average is " + str(total/count))
Explanation:
Firstly, we create four variables, <em>total</em> , <em>count,</em> <em>neg</em> and <em>pos </em>(Line 1- 4). This is to prepare the variable to hold the value of summation of input integer (<em>total</em>), total number of input number (<em>count</em>), total negatives (<em>neg</em>) and total positives (<em>pos</em>).
Next, we prompt user for the first integer (Line 6).
Create a sentinel while loop and set the condition so long as the current input number, <em>num</em> is not equal to zero. the program will just keep adding the current <em>num</em> to total (Line 9) and increment the count by one (Line 10).
if <em>num</em> smaller than zero, increment the <em>neg</em> by one (Line 13) else increment the <em>pos </em>by one (Line 15). This is to track the total number of positives and negatives.
Finally, we can display all the required output (Line 20 - 23) using the Python built-in function <em>print()</em> when user enter 0 to terminate the while loop. The output shall be as follows:
The number of positives: 3
The number of negatives: 1
The total is 5
The average is 1.25
Answer:
Too much sitting-affects the back and makes our muscles tight
Carpal tunnel and eye strain-moving your hand from your keyboard to a mouse and typing are all repetitive and can cause injuries
Short attention span and too much multitasking-As you use a computer and the Internet and get immediate answers to your questions and requests, you become accustomed to getting that quick dopamine fix. You can become easily frustrated when something doesn't work or is not answered in a timely matter.
