83. Which option is not possible for the following function call?
    

    func(&stru.num); //where stru is a variable of type struct and num is the member of the struct.
    

1. 1. Individual member can be passed by reference in a function

   
   
   

   2. Individual member’s address can be displayed in structure

   
   
   

   3. Compiler can access entire structure from the function

   
   
   

   4. All of above

   
   
   

   5. None of these

84. What will be the output of the following C code?
    

    #include <stdio.h>
        struct Example
        {
            int n;
        } e;
        void fun(struct Example);
        main()
        {
            e.n = 101;
            fun(e);
            printf("%d\n", e.n);
        }
        void fun(struct Example e)
        {
            e.n = 1;
        }
    

1. 1. Compilation Error

   
   
   

   2. Garbage value

   
   
   

   3. 101

   
   
   

   4. Nothing

   
   
   

   5. None of these

    #include <stdio.h>
        struct option
         {
            int n1;
            int n2;
        };
        int main()
        {
            struct option opt1[] = {101, 97, 32, 91, 52, 91};
            struct option *ptr1 = opt1;
            int n1 = (sizeof(opt1) / 5);
            if (n1 == 3)
                printf("%d %d\n", ptr1->n1, (ptr1 + n1 - 1)->n1);
            else
                printf("False\n");
        }
    

1. 1. Undefined behaviour

   
   
   

   2. Compilation Error
