Answer:
Add the hex value to the appropriate base-
16 place-value column: 2 in the 16 column; D in the 1 column.
Work out the hex digits and their representation in denary-
2 = 2 in denary; D = 13 in denary.
Multiply with the place value: 2 x 16 = 32; 13 x 1 = 13.
Add the values together: 32 + 13 = 45 in denary.

Explanation:
The language I use would do it as
h1$ = copy(h$,1,3)
This may not satisfy you, because your language could be quite different. You might want an input statement of some kind that would define h$. This assumes that somewhere h,h1 are declared as strings.
You also have to know how to read an input. My language uses readln(input,h)
and how to write it on the screen write(h1) or writeln(h1)
<u>Swap files </u>contain(s) remnants of word processing documents, e-mails, Internet browsing activity, database entries, and almost any other work that has occurred during past Windows sessions.
Explanation:
I order to simulate extra space an operating system like windows use hard disk space in order to stimulate extra memory.When a computer system is running low with the memory space the swap file swaps a section of RAM onto the hard disk in order to obtain a free memory space.
This Process at times results in slowing down of the computer computer considerably.
<u>The combination of RAM and swap files is known as virtual memory.</u>
It is due to the use of virtual memory that our computer is able to run more programs than it could run in RAM alone.
