The good() method of ios class in C++ is used to check if the stream is good enough to work. It means that this function will check if this stream has raised any error or not. Syntax:
bool good() const;
Parameters: This method does not accept any parameter. Return Value: This method returns true if the stream is good, else false.
Time Complexity: O(1)
Auxiliary Space: O(1)
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:
is stream good: 0
