Detailed Explanation:

In classic Visual Basic menu captions, an ampersand (&) placed immediately before a character marks that character as the access-key mnemonic.

The marked character is typically underlined and can be activated with the keyboard (often using Alt).

Detailed Explanation:

mkdir p creates directory p, and cd p changes into it.

touch q and touch r create empty files named q and r.

ls > a.txt redirects the directory listing into a.txt. Because the redirection file is created before ls runs, the listing normally includes a.txt, q, and r (assuming the usual alphabetical listing and no unusual aliases/options).

grep "q" a.txt prints the line containing q.

Detailed Explanation:

C++ permits overloading operators such as &, !, and %.

The scope-resolution operator :: cannot be overloaded.

Other non-overloadable operators include ., .*, ?:, and sizeof.

Detailed Explanation:

HTTP status code 403 means Forbidden: the server understood the request but refuses to fulfil it.

404 means Not Found, 500 means Internal Server Error, and 503 means Service Unavailable.

A 403 response is in the 4xx client-error class, not the 5xx server-error class.

Detailed Explanation:

The for loop starts with i = 2 and continues while i < 9.

The values added to sum are 2, 3, 4, 5, 6, 7, and 8.

Their sum is 2 + 3 + 4 + 5 + 6 + 7 + 8 = 35.
