Example 1:
CPP
// C++ code to demonstrate // the working of good() function #include <bits/stdc++.h> using namespace std; int main() { // Stream stringstream ss; // Using good() function bool isGood = ss.good(); // print result cout << "is stream good: " << isGood << endl; return 0; } |
Output:
is stream good: 1
Example 2:
CPP
// C++ code to demonstrate // the working of good() function #include <bits/stdc++.h> using namespace std; int main() { // Stream stringstream ss; ss.clear(ss.eofbit); // Using good() function bool isGood = ss.good(); // print result cout << "is stream good: " << isGood << endl; return 0; } |
Output:
