Answer 1

Answer:

Hello the options to your question is missing here are the options

• 6

• 7

• 8

• NaN

answer : 7

Explanation:

The value of the num_colors variable is 7 and this because you have to neglect the fact that there is no termination symbol at the end of the assignment operation in the code.

But when we consider the none existence of a termination symbol at the end of the assignment operation in the code, the code will generate a syntax error instead of a value.
