#include <iostream>
int main()
{
using namespace std;
char ch;
int count = 0;
cin.get(ch); // attempt to read a char
while (cin.fail() == false) // test for EOF
{
cout << ch; // echo character
++count;
cin.get(ch); // attempt to read another char
}
cout << endl << count << " characters read\n";
return 0;
}
上面的代碼生成以下結果。
#include <iostream>
int main(void)
{
using namespace std;
int ch; // should be int, not char
int count = 0;
while ((ch = cin.get()) != EOF) // test for end-of-file
{
cout.put(char(ch));
++count;
}
cout << endl << count << " characters read\n";
return 0;
}
