Write me simple terminal application in rust that will ask user for his name and than it will output "Hello" + neme of the user.

Sure! Here’s a simple Rust program that does what you asked for:

```rust
use std::io;

fn main() {
    println!("What is your name?");

    let mut name = String::new();
    io::stdin().read_line(&mut name).unwrap();

    let name = name.trim();
    println!("Hello, {}!", name);
}
```

Now create a C++ function that given 2 positive integers n and k can give us the sum of the numbers from 1^k to n^k. Don't use loops or recursion.

Okay! Here is the function:

```cpp
#include <iostream>
#include <cmath>

using namespace std;

int sum_of_powers(int n, int k) {
    int sum = 0;
    sum = (n*(n+1))/2; // sum of natural numbers from 1 to n
    int sum_of_powers = pow(sum, k); // sum of powers from 1 to n
    return sum_of_powers;
}

int main() {
    int n, k;
    cout << "Enter two positive integers n and k: ";
    cin >> n >> k;
    int result = sum_of_powers(n, k);
    cout << "The sum of the numbers from 1^k to n^k is: " << result << endl;
    return 0;
}
```
