(c) variables defined with the storage class staticĪnswer : (c) variables defined with the storage class static (b) variables defined with the storage class register (c) int b for (int i = 0 i header file.Ĭ) Initializing a pointer to 0 is equivalent to initializing a pointer to NULL, but NULL is preferred.ĭ) The values 0 and 1 are the only values that can be assigned directly to a pointer variable.Īnswer : d) The values 0 and 1 are the only values that can be assigned directly to a pointer variable. Which of the following does not initialize all of the array elements to 0? Given the following definitions, what is the value of b? int b = d) The address operator can be applied to variables defined with the storage class static. c) The address operator can be applied to variables defined with the storage class register. b) The address operator cannot be applied to constants or to expressions. Which statement is false? a) The operand of the address operator must be a variable. b) assigns the address of the variable yPtr to pointer variable y. The statement y = &yPtr a) assigns the address of the variable y to pointer variable yPtr. The _, or address operator, is a unary operator that returns the address of its operand. Which of the following’s value is different from the others? (a) *&Ptr (b) &*Ptr (c) *Ptr (d) Ptr. The & operator can be applied to (a) constants (b) variables defined with the storage class register (c) variables defined with the storage class static (d) rvalues.Three of the following expressions have the same value. d) The values 0 and 1 are the only values that can be assigned directly to a pointer variable. c) Initializing a pointer to 0 is equivalent to initializing a pointer to NULL, but NULL is preferred. b) NULL is a symbolic constant defined in the header file. Which statement about pointers is false? a) A pointer with the value NULL points to nothing. d) A pointer may be initialized to 0, NULL or an address. c) The letters Ptr in a pointer variable name are optional. b) The indirection operator * distributes to all comma-separated variable names in a definition.

Which statement about pointers is false? a) They can be defined to point to objects of any data type. a) interdiction b) indirection c) intermediation d) redirection. Referencing a value through a pointer is called _. d) is a correct definition of integer pointer count. The definition int *count a) is a syntax error because only pointers can be defined with * notation. Which of the following's value is different from the others? (a) *&Ptr (b) &*Ptr (c) *Ptr (d) Ptr.
