Answer 1

The solution to your problem is:-

As there is no mention of any programming language I have used python as my programming language.

code for the above program is:-

s=0 # used for storing addition result.
while(True): # running an infinite loop.
   k=int(input("enter a positive number: ")) # taking input from the user.
   if(k>0): # checking the number is a positive is or not.
       s=s+k # if it is true then add the numbers.
   elif(k==0): # if it is 0 then stop asking the numbers and add them
       break   
   else:
       print("Please enter a positive number ") # if is the negative number it will prompt the user to enter a positive number again and again

print(s) # printing the sum.

Output for the above program is:-
