Question 8 :
Answer: d ( underscore)
reason:
An indentifier is a user-defined word. It may have both letters or digits or numbers. It is alpha numeric. And,
an identifier starts with a letter or an UNDERSCORE.
So, the answer option is the underscore.
Question 9:
Answer: C y/x*2
Reason:
Given x,y are two variables.
In any mathematical operation, either addition, or subtraction or division or multiplication, PARANTHESIS is mandetory and helps in preventing from commiting mistakes.
y/ x*2 is not the same as y/ ( x*2)
