如何获取getline字符串中的某个单词？

Question

How can someone get only a certain word in a string of a getline method? For example:

Test.txt:

 hi guys
 im @@Paul \t\t [GET THIS]

---

string line;
string word;
ifstream file ("test.txt");

if (file.is_open()) {
    while (getline(file, line)) {
        if (line.find("@@Paul") != string::npos) {
            strcpy(word, line.c_str());
        }
    }
}

How can I code it so when I find @@Paul it only takes the characters ( [GET THIS] ) after the double tab ( \\t\\t )?

Answer 1

this is definition of getline function: istream& getline (istream& is, string& str, char delim);

Delim is a delimitier which stops getline from reading the stream after to the given character. so you can do something like this:

string trash;
string properline;

getline(file, trash, '\t');
getline(file, trash, '\t'); //second tab, still trash
getline(file, properline);
