  a.x = 5;
  a.y = 10;
}

Question 2

int sum(int * array){
  int sum=0;
  for(int i=0;i<sizeof(array);i++){
     sum +=  array[i];
  }
  return sum;
}

int main(){
  int array[] = {1,2,3,4,5,6,7,8,9,10};
  int s = sum(array);  
  printf("%d\n",s);
}

Question 3

Select the correct memory diagram for the following program at point (1):

int main(){
   int array[3];
   int *p = &array[1];
   int *q = &array[2];
   
   array[0] = 2;
   *p = 8;
   *q = 4;

   array[2] = 12;  // <- point (1)
   
   int ** r; 
   r = &q;
   **r = 16;// <- point (2)
}

Question 4

Select the correct memory digraion for the program above at point (2)

Question 5

   struct foo{
      int i;
      int j;
      struct bar * BAR;
   };
