Answer:
Secondary storage is needed to keep programs and data long term. Secondary storage is non-volatile , long-term storage. Without secondary storage all programs and data would be lost the moment the computer is switched off.
External storage enables users to store data separately from a computer's main or primary storage and memory at a relatively low cost. It increases storage capacity without having to open up a system.
It’s something that reflects off something
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
