Felicity wants to take her DSLR camera on vacation, but she can take only one bag. Why is taking a DSLR camera with her not a good idea?

Answers

The reason why taking a DSLR camera with her is not a good idea is because a DSLR camera and its accessories usually require their own bag and can be heavy.

A digital single-lens reflex (DSLR) camera is being used by photographers especially for shooting stunning landscapes or portrait images. DSLR cameras are durable and can be used with a variety of lenses and attachments, they have a long battery life, and provide faster shooting speeds with better autofocus.

Therefore, the reason why taking a DSLR camera with her is not a good idea is because a DSLR camera and its accessories usually require their own bag and can be heavy, whereas she can only take one bag with her.

For a list of numbers entered by the user and terminated by 0, find the sum of the positive numbers and the sum of the negative numbers. C++ language only.

Answers

Answer:

Following are the program in the Python Programming Language

#set variables to 0

positive_sum=0  

negative_sum=0  

#print message  

print("Enter 0 to terminate")  

#set the while loop  

while(True):  

#get input from the user  

num=float(input("Enter positive or negative numbers: "))  

#set if statement to check condition  

if(num==0):  

  break  

elif(num>0):  

  positive_sum+=num  

else:  

  negative_sum+=num  

#print output with message  

print()  

print("sum of positive numbers: ", positive_sum)  

print("sum of negative numbers: ", negative_sum)  

Output:  

Enter 0 to terminate  

Enter positive or negative numbers: 1  

Enter positive or negative numbers: 3  

Enter positive or negative numbers: 5  

Enter positive or negative numbers: -7  

Enter positive or negative numbers: -2Enter positive or negative numbers: 0  

sum of positive numbers:  9.0  

sum of negative numbers:  -9.0

Explanation:

Here, we set two integer data type variables "positive_sum", "negative_sum" and initialize to 0.

Then, we set the while infinite loop inside the loop.

Set a variable "num" and get input from the user in it.

Set the if conditional statement and check condition the variable "num" is equal to 0 then, loop will terminate.

Set the elif statement and check condition the variable "num" is greater than 0 then, add that input and store in the variable "positive_sum"

Otherwise, add that input and store in the variable "negative_sum".

Finally, we print the output with the message.
