what is the best way to put a letter into an array

[Parrish666]

I am wondering what is the best way to put letters (a-z) into an array or a vector, instead of forcing the letter into the array manually. I would like to use a for loop to do so. Here is what I got:

vector<char>aplha(26);
     for(int x=0; x<aplha.size();x++)
     {
     
     }

I was thinking about aplha[x]= but I am not sure what to make it equal to in the loop.

'a'+x

thank you, that helped. i was also using functions as well. so that made it a little harder.
