Why is this program printing the reverse of the expected result?

Question

#include <bits/stdc++.h>
using namespace std;
int main()
{
     string in_code;
     std::cin >> in_code;
     int word;
     word = in_code.find(" ");
     in_code.erase(0, (word + 1));
     cout << in_code << endl;
}

This program should return "is_a_good_boy" when I give input "Jhon is_a_good_boy". But it prints "Jhon". Help me solve this, please.

You probably should approach this with getline in order to capture the whole line entered as well as do validation when using string.find

Commented example below.

#include <string>
#include <iostream>

int main()
{
    std::string in_code; //String to store user input
    std::getline(std::cin, in_code); //Get user input and store in in_code

    int word = in_code.find(" "); //Get position of space (if one exists) - if no space exists, word will be set to std::string::npos
    if (word != std::string::npos) //If space exists
    {
        in_code.erase(0, word + 1); //erase text before & including space
        std::cout << in_code << std::endl; 
    }
    else
    {
        std::cout << "The entered input did not contain a space." << std::endl;
    }
    return 0;
}
