To do: Using the C++ eof(), char_traits class member to returns the end-of-file (EOF) character in  C++ programming

To show: How to use eof() member function of the char_traits class to returns the end-of-file (EOF) character in  C++ programming

 

// the char_traits class member, eof() example

#include <string>

#include <iostream>

using namespace std;

 

int main(void)

{

char_traits <char>::int_type int0 = char_traits<char>::eof();

cout<<"The eof return is: "<<int0<<endl;

char_traits<char>::char_type chs = 'R';

char_traits<char>::int_type int1;

int1 =char_traits<char>::to_int_type(chs);

cout<<"char_type chs "<<chs<<" = to int_type "<<int1<<endl;

char_traits <char>::int_type int2 = char_traits<char>::eof();

cout<<"The eof return is: "<<int2<<endl;

return 0;

}

 

Output example:

 

The eof return is: -1

char_type chs R = to int_type 82

The eof return is: -1
