C++ how to input certain things in vector

I have a empty vector that I need to fill with binary numbers 1 and 0, and when user inputs something other then 0 and 1 the size of vector is complete. I tried something like this:

#include "pch.h"
#include <iostream>
#include <vector>

using namespade std;

bool task1() {
vector<int> binV
int input = 0;

for (int i = 0; i < binV.size; i++) {
    cout << "Enter binary number: " << " ";
    if (input == 1 && input == 0) {
        cin >> input;
        binV.push_back(input);
    }
    else {
        cout << "Wrong input, the size of vector is complete";
    }
}
return 0;
}
int main() {
    task1();
}

I made simple loop for inputing and made this if/else statement which is incorrect I presume but didn't find solution to my task and I ran into code problems C2446 and C3867 which I don't understand since I'm not expert in C++
