They are both technically right, but the majority of people would say 'an' STD. When talking about something that begins with a vowel-sounding letter, we tend to use 'an' - it just sounds better to say "an automobile" than "a automobile" after all. That's the reason why we have that a/an difference, the way the phrase sounds.
The 'S' in STD stands for 'Sexual' and would therefore be 'a Sexual' if vocalising the unabbreviated word. But when it is abbreviated, it is pronounced 'Ess' and therefore begins with a vowel-sounding letter. It therefore sounds more natural to say 'an STD' though neither version is more grammatically correct than the other.
It is a STD.

"A" is used when the following word starts with a consonant or a letter that sounds like one. (Ex: "one" starts with a vowel but it sounds like the letter "W" which is a consonant so it would be "A one" instead of "An")
"An" is used when the following word starts with a vowel or a letter that sounds like one. (Ex: "hour" starts with a consonant but it sounds like "Our" which starts with a vowel, therefore it would be "An".
Now as for "STD", when saying it you would say "An STD" because the "S" is pronounced sounding like "es" instead of "ss" but if saying "sexually transmitted disease" it would be "A". I hope this helps!

How do you make quiz master in c plus plus programm?
Assuming the quiz is a simple question/answer style quiz, use a map to associate question strings with answer strings. In order to prevent people from simply examining the program resources to get the answers, you should also consider encrypting the map. For multiple choice quizzes, use a structure containing the question string, a vector of strings for the possible answers and an unsigned integer to identify the correct answer (as an index into the vector).
