ios good() function in C++ with Examples
  • Last Updated : 02 Sep, 2019

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.

Example 1:






// 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:




// 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
