#include <iostream>
#include <fstream>

using namespace std;

int main() {
    int a;
    char b;
    ifstream in("a.txt");

    if (!(in >> a))
        in >> b;
    if (!(in >> a))
        in >> b;
    in >> b;
    in >> b;

    cout << a;
    cout << b;
}//source code

5 a b c d e
//a.txt

1. If there is a int in the file I want to read it as int and


2. If there is a char in the file I want to read it as char.


3. why can't read 'char b' after try to read b as int?
