Dictionary like setup

[shurix]

Hi,I am new to c++ and I am stuck.
I have a text file. There are word pairs separated with "," formated like
word translation,word2 translation2,word3 translation3
I need to read them letter by letter from file and store them in 2 dimension array so I can compare them later with other words like a dictionary.
I got the reading part right but can't figure it out how to store them.

char c1;
fstream fin1 ("f2.txt", ios::in);
fin1.get(c1);
while(fin1) {


};

So how can I build 2 dimension array letter by letter?
