19.8.1.1. Exercises: static_cast and const_cast

In Example 19.11 try moving the
```
const int N = 22; 
```
above or below
```
int main() { 
```
Observe and explain the difference in output.

Predict the output of Example 19.12.

Example 19.12. src/casts/constcast2.cpp

#include <iostream>

void f2(int& n) {
    ++n;
}

void f1(const int& n, int m) {
    if (n < m) 
        f2(const_cast<int&>(n));
}

int main() {
    using namespace std;
    int num1(10), num2(20);
    f1(num1, num2);
    cout << num1 << endl;
}

Remove the const_cast from the call to f2() inside f1(), and predict the output again.
