Answer:
Only option 6 and 7 are not valid but the option 1,2,3,4,5 and 8 are valid.
Explanation:
Identifier means the name which is defined for any programming language. There is a need for a variable in any programming language which is used to store the value to perform the calculation with the help of instruction.There are 2 rules which state that how a user can define an identifier. They are as follows--
- The identifier name must not start with any number.
- The identifier name can not hold the special symbol except underscore(_) either in start point or any other place.
The above question wants to know that which option is valid or not which are as follows--
- Option 6 and 7 are not valid because the identifier of option 6 starts with number and the identifier of option 7 hold space.
- Option 1,2,3,4,5 and 8 are valid because the identifier of these options has not neglected the rule to declare the identifier which is defined above.
