C++ for advanced programmers

C++ supports primarily static, but also dynamic type checking!

C++ is a weakly-typed system!

C++ is a type-safe language!

C++ supports both manifest and inferred typing!

What is the output for sum?

#include <iostream>
using namespace std;

int main() {
    int sum = 0;

    for (int i = 0, j = 2; i < 6 & j < 10; i = j - i, j++) {
        sum += j;
    }

    cout << sum;

    return 0;
}

What is the output?

#include <iostream>
using namespace std;

int fun(int a, int b) {
    if (a == 0) {
        return b;
    } else {
        return a + fun(a - 1, b);
    }
}

int main() {
    cout << fun(1, 2);

    return 0;
}

What is the output?
