Find specific string of lines in a text file

[roidbeginner]

I am trying to print a specific line from a textfile

e.g
I have a text file called info.txt and inside it contains the id,item name, price, quantity

1,shirt,100,10
2,pants,50,9
3,pen,20,8

I know how to find a specific word at the line in the file but how do I find and print out the specific line e.g(print out just the entire contents of line 2)?

    string temDescription;
    ofstream fout;
    
    int curLine = 0;
    
    ifstream readFile("info.txt");
    cout << "Enter Item Description: "; 
    cin.ignore();
    getline(cin, itemDescription);
    
    while(getline(readFile, line)) {
        curLine++;
        if (line.find(itemDescription, 0) != string::npos) {
             cout << "found: " << itemDescription << " at " << "line: " << curLine << endl;
        }
    }
    readFile.close();

Please advise. thanks
