For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }

Part 5. Operator Overload: add Next, you will add the ability to use the addition operator (+) in conjunction with Simpy objects and floats. You will implement add such that the left-hand side operand of an addition expression can be either a simpy object or a float value using a Union type. The add_method should return a new Simpy object and should not mutate the object the method is called on. When the right-hand side of an addition expression is also a simpy object, you should assert that both objects' values attributes have equal lengths. Then, you should produce a new simpy object where each item in its values attribute corresponds to the items of the original Simpy objects at the same index added together. For example: a = Simpy([1.0, 1.0, 1.0]) b = Simpy([2.0, 3.0, 4.0]) c = a + b print(c) # Output: Simpy([3.0, 4.0, 5.0]) When the right-hand side of an addition expression is a float value, you should produce a new simpy object where each item corresponds to the item at the same…

Determine whether the following array declarations are valid. If a declaration is valid, write VALID. If it is invalid, you can make assumptions and write a correct declaration.

O list->next = p; delete p; O p = list->next; %3D list->next = p->next; delete p; p = list->next; list = p->next; delete p; O None of these O p = list->next; %3D list->next = p; %3D delete p;
