How to read a comma separated words from a file and assign it to variables in c++?

I have been looking for a good approach to solve this issue, but many examples are when words are separated by spaces and it makes a solution easier, like in this example:

ifstream fin(“marks.txt”);

    string name;
    int var1;
    int var2;
    int var3;

    while (fin >> name >> var1 >> var2 >> var3)
    {
        /* do something with name, var1 etc. */
        cout << name << var1 << var2 << var3 << “\n”;
    }

but what if my file has the following:

word1,word2,word3,word4,word5
word6,word,word,word,word,word

How should implement a code for this! I will appreciate any help, newbie in c++ Thanks in advance
