Помогите пожалуйста решить на языке C++

#include <iostream>

using namespace std;

int main()
{
cout << "Hello, world!" << endl;
return 0;
}

#include <iostream>
using namespace std;
const int N =300;
int main()
{
int n, m;
//2 cicle
for(int i=100; i<=N; i++)
{
n= i % 10;
for(int j=100; j<=N; j++)
m = n%10;
cout<<m<<" ";
}
// 1 cicle
cout<<endl;
for(int i=100; i<=N; i++)
cout<<i%10<<" ";
cin.get();
}

#include <iostream>
#include <string>
using namespace std;
int main() {
unsigned n, tmp, digit, signs;
const unsigned zero = 0, one = 1, two = 2, three = 3, ten = 10, hundred = 100;
do {
cout << "n: ";
cin >> n;
} while (n < hundred);
// 1. Two loops
tmp = n;
signs = zero;
while (tmp) {
tmp /= ten;
++signs;
}
tmp = n;
for (unsigned i = three; i < signs; ++i) tmp /= ten;
digit = tmp % ten;
cout << "1: " << digit << endl;
// 2. One loops
tmp = n;
signs = int(log10(tmp)) + one;
for (unsigned i = three; i < signs; ++i) tmp /= ten;
digit = tmp % ten;
cout << "2: " << digit << endl;
// 3. Bonus!
string t = to_string(n);
cout << "3: " << t.at(two) << endl;
cin.sync();
cin.get();
}

#include <iostream>using namespace std;int main(){cout << "Hello, world!" << endl;return 0;

using UnityEngine;
using System.Collections;

public class Controls : MonoBehaviour
{

void FixedUpdate ()
{
float moveHorizontal = Input.GetAxis ("Horizontal");
float moveVertical = Input.GetAxis ("Vertical");

Vector3 movement = Vector3 (moveHorizontal, 0.0f, moveVertical);
Rigidbody.AddForce (movement);

}

}
