Answer:
D. End-User Programmer.
Explanation:
A stack data structure is used to holds data for programs. The first data to go into a stack is always the last to be extracted (First-in-Last-out). Data is read into the stack with the push function and retrieved with the pop function.
When the stack is empty, it means there are no data left to pop from it. If a pop function is issued at this time, the program conventionally throws an error, there is no need for the end-user to write an exception handler for it because the end-user programmer has done that already.

Answer:
Four times traveling 40,12345 mts
Explanation:
We can express this as a sum as follows
The first term is the dropping part and the second is the upward motion. this sums up to 40,12345 m after bouncing four times. As a program we could write using the while loop.
distance=0;
i:=0;
while distance<40 do
i:=i+1;
distance:=distance+ 
end while;
Here the answer is in i and the closest distance traveled after reaching 40 is in the variable distance.
You can use internal style definitions with the <style> tag:
<style>
body {
color: red;
font-style: italic;
font-size: 12pt;
font-family: Arial;
font-weight: bold;
}
</style>
This gives you red italic text of 12pt using the Arial font.
Answer:
PNG, GIF
Explanation:
On a Web page, we'll assume he'll have simple graphic elements like icons, or other simple low-resolution and a lower number of colors (256-), these are usually better saved in GIF format to take less space, just because of the smaller color map, but PNG could also do a great job and it offers transparency as well (like GIF does).
For more complex elements (larger size and/o more colors like photos), the best format to save them is probably the PNG one. They will be compressed but still offer a great quality.
