A signed integer is the best option. In some systems, the value -1 can indicate that no combobox item is selected, so you need to allow for negative values.
Answer:
b. & Puihaha
Explanation:
PHP variables are supposed to start with a $ sign.
Other rules followed by PHP variables are:
Starting character in variable name (after $) must be letter or _.
Other characters in variable names can be letters,numbers or _.
a. $_Puihaha
c. $Pui_haha
d. $Puihaha
satisfy these rules.
Whereas , b. & Puihaha does not satisfy as it starts with '&'. Moreover it also contains an invalid space character in the variable.
Using the computational language in JAVA it is possible to write a code that at least passes an unspecified number of integers

Answer:
Following are the program in the Python Programming Language.
#declare variables and initialize to 0
s=0
n=0
avg=0
#set the infinite while loop
while(True):
#get input from the user
score=input()
#set if statement to break loop
if(score =="stop"):
break
#otherwise, perform calculation
else:
n+= 1
s=s+ int(score)
avg= s/n
#print average of the input
print ('average: ',avg)
<u>Output</u>:
58
96
34
15
stop
average: 50.75
Explanation:
<u>Following are the description of the program</u>.
- Firstly, set three variable that is 's' for sum, 'n' for count and 'avg' for average and initialize them to 0.
- Set the infinite while loop and inside it, set variable 'score' that get input from the user then, set the if conditional statement for break the loop, otherwise we calculate the sum of the user input and calculate its average.
- Finally, we print the result with message.
