Examples of StringStream in C + +

Contains header files #include <sstream>

Initialization can be assigned using clear (), str ();

can use << input and >> output

String S;stringstream ss;int A, B, C;getline (CIN, s); Ss.clear (); Ss.str (s); SS >> a >> b >> c; The default space here is a direct word, and even if the type of ABC is different, it is equivalent to flexible type conversion

String S;stringstream ss;int N, I, Sum, a;cin >> n;getline (CIN, s); Read line break for (i=0; i<n; i++) {    getline (CIN, s);    Ss.clear ();    SS.STR (s);    sum=0;    while (1)    {        ss >> A;        if (Ss.fail ()) break; Fail () to determine if the sum+=a is in the end        ;    }    cout << sum << Endl;}

　　

    StringStream is convenient for split      . String A, B, C, D;      String lines= "ADFA;ASDFASD;FASDF;CCC";       StringStream line (lines);  Getline can be initialized directly    (line, A, ' f ');      Getline (line, B, '; ');      Getline (line, C, '; ');      Getline (line, d);     Paired with different getline    cout<< "a =" <<a<<endl;      cout<< "b =" <<b<<endl;      cout<< "c =" <<c<<endl;      cout<< "D =" <<d<<endl;  

There is another problem: the default participle here is a space, then if it is other such as comma how to do
