The eof() method of ios class in C++ is used to check if the stream is has raised any EOF (End Of File) error. It means that this function will check if this stream has its eofbit set. Syntax:
bool eof() const;
Parameters: This method does not accept any parameter. Return Value: This method returns true if the stream has eofbit set, else false.
Time Complexity: O(1)
Auxiliary Space: O(1)
Example 1:
CPP
// C++ code to demonstrate // the working of eof() function #include <bits/stdc++.h> using namespace std;
int main()
{ // Stream
stringstream ss;
// Using eof() function
bool isEOF = ss.eof();
// print result
cout << "is stream eof: "
<< isEOF << endl;
return 0;
} |
Output:
is stream eof: 0
Example 2:
CPP
// C++ code to demonstrate // the working of eof() function #include <bits/stdc++.h> using namespace std;
int main()
{ // Stream
stringstream ss;
ss.clear(ss.eofbit);
// Using eof() function
bool isEOF = ss.eof();
// print result
cout << "is stream eof: "
<< isEOF << endl;
return 0;
} |
Output:
is stream eof: 1
