Question

question # 6
multiple select
which of the following are valid variable names? select 3 options.
2nd_num
num1
playerscore
player@
player_score

Explanation:

Variable names in programming usually cannot start with a number. They can contain letters, numbers, and underscores. Special characters like '?' are not allowed in most cases. "2nd_num" is invalid as it starts with a number. "player?" is invalid due to the '?' character. "count", "playerScore", and "player_1" are valid as they follow naming rules.

Answer:

count
playerScore
player_1
