def get_last_cursor(c):
    """Return last cursor beneath cursor c.

    Practically, if c is root of an AST, right most leaf is returned.

    For this snippet:
    int main() {
        int a = 0;
        for (int i = 0; i < 3; i++) {
            a += 1;
        }
    }

    It returns the cursor that represents integer literal 1.

    In this example:
    int main() {
        int a = 0;
        for (int = 0; i < 3; i++) {
            a += 1;
        }
    }

    As there is an error in for statement it returns the last one correct.
    In this case, that is cursors that represents 0 in line 2 of the snippet.
