ios eof() function in C++ with Examples
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.
Example 1:
// 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:
// 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
