Explanation / Answer

Ans 6.

We have certain rules to name a Variable, the rules are: -

So, in the question given above, CS 101, cannot be used as a Variable name, as it has spaces, and does not satisfy the rules of Variable Naming Conventions.

All other can be used as the Variable Names.

Ans.

If A= {2:3:8;4 2 8:3 5 1}

So, after a semi colon sign we change a line or switch to next part, so in a given set, as 5 is in the 3rd part and is the 2nd element of the 3rd part, So, to return 5, we will use A (3,2), that is the C) option, as this will call the 3rd part and then the 2nd element of it.

This is all for the questions submitted by You.
