How to read in individual characters from txt.file in C++?

Question

I have a txt file that contains individual characters line by line. I am kind of confused as to how to read that line by line when the getline function takes in string?

Also would it be possible to store char in a vector? Or would it still work if I stored those individual characters as strings?

Answer 1

code show as below:

vector<char> res;
int count = 0;

ifstream fin;
fin.open("***.txt");
string str;
while (!fin.eof())
{
   getline(fin, str);
   res[count++] = str;
}
fin.close();
