Question

Correct C++ function and main file separately for the following question:

Given a positive decimal number, write a function that transforms it into binary, and prints out the result. You may assume that the string contains at least 1 and no more than 9 decimal digits. The output should only include the binary digits followed by a new line.

Hint: You might need to convert a string to integer. Have a look at the stoi(string) in the C++11 string library. If you need to compile with C++11, include the compilation flag -std=c++11 in your compile command.

Signature: void print_as_binary(std::string decimal_number)

#include <iostream>
#include <cstring>
using namespace std;

void print_as_binary(std::string decimal_number) {
        int num = stoi(decimal_number);

        string s = "";
        while(num != 0) {
                s = (char)('0' + (num%2)) + s;
                num = num / 2;
        }
        cout << s << endl;
}

int main()
{
        print_as_binary("23432");
        return 0;
}

Please upvote, as i have given the exact answer as asked in question. Still in case of any issues in code, let me know in comments. Thanks!
