Computer Multi Threading In C Plus Plus Difficulty: Medium

The following C function takes a single-linked list of integers as a parameter and rearranges the elements of the list. The function is called with the list containing the integers 1, 2, 3, 4, 5, 6, 7 in the given order. What will be the contents of the list after the function completes execution? struct node { int value; struct node *next; }; void rearrange(struct node *list) { struct node *p, * q; int temp; if ((!list) || !list->next) return; p = list; q = list->next; while(q) { temp = p->value; p->value = q->value; q->value = temp; p = q->next; q = p?p->next:0; } } What type of members are not serialized? Choose the appropriate code that counts the number of non-zero(non-null) elements in the sparse array. What will be the output of the following Python code? d = {0: 'a', 1: 'b', 2: 'c'} for x, y in d: print(x, y) What will be the output of the following C++ code? #include <iostream> using namespace std; const int SIZE = 10; class safe { private: int arr[SIZE]; public: safe() { register int i; for (i = 0; i < SIZE; i++) { arr[i] = i; } } int &operator[](int i) { if (i > SIZE) { cout << "Index out of bounds" <<endl; return arr[0]; } return arr[i]; } }; int main() { safe A; cout << A[5]; cout << A[12]; return 0; }
