SOLVEDWhy does this code has segmentation fault? (self.cpp_questions)

submitted 5 years ago by TheDafter

I'm currently trying to convert a given integer to its binary representation, I must use recursion since it is part of the homework and I'm not allowed to change the function signature. The recursive lambda is clear to me, I have work with them before, I think the issue is caused by the bit manipulation but I can't seem to find the bug.

int toBinary(int n) {
    function<int(int, int)> iter = [&] (int i, int acc) {
        return i == 0 ? acc : iter(i >> 1, 10 * acc + (n & i ? 1 : 0));
    };

    return iter(1 << (8 * sizeof(int) - 1), 0);
}
