Shortening and facilitating the creation of programs

lukakap (5)
I made a program that helps me learn german.I speak just serbian,that you should not confuse about text in quotes,and not so good english.Is there any way to replace "a, a1, a2, a3" with something constant or at least variable and save time?

Thank you very much!!!

Note that I made a mistake in my previous post. On line 13 it should read
 
 
auto &answer = kv.second;

Also, come to think of it an std::map was not the most ideal data structure for this problem.

Could you tell me to re-enter the word if i am wrong?

I'll let you figure that one out.
