public:

            cout << "incorrect binary format" << endl;
            exit(0);
        }
    }
}

void binary :: once_compliment(void) {
    for(int i = 0; i < s.length(); i++) {
        if(s.at(i) != '0') {
            s.at(i) = '1';
        }
        if(s.at(i) != '1') {
            s.at(i) = '0';
        }
    }
}

void binary :: display(void) {
    cout << "displaying binary number";
    for(int i = 0; i < s.length(); i++) {
        cout << s.at(i);
    }
}

int main() {
    binary b;
    b.read();
    b.chk_bin();
    b.once_compliment();
    
    return 0;
}

working well

but isnt asking for input of the string

[wild shale]

what other input apart from the "enter a binary number" string?

[fierce zodiac]

oh hell yeah

so we basically used that input as a string to execute the code further

thanks a ton

[wild shale]

I did nothing but yw

!solved
