/* we write a program to convert sum to two integers into binary 
and then we converted into string
*/
#include <iostream>
using namespace std;

int main() {
    int a = 0;
    int b = 10;
    a += b; 
     //a = a+b; the above is line is same as this;

    string output; // we declare a string variable

    do {
        output = to_string(a % 2) + output; // to_string() is function to convert into string
        a /= 2;
    } while(a > 0);
    cout<< output;
}
