Pointers both as variables and function parameters are used to store addresses. Well in fact these brackets are a dereferencing operator known as offset operator. Choose the right option string x y.

Both x and y are pointers to string types. Which of the following is not true. D If a pointer points to an array the pointer does not know how many elements are in the array.

An address or NULL. In the following code lines A is an int type variable D is variable of type double and ch is a variable of type char. A If a pointer points to an array it can be used in place of the array name.

The address of an integer variable can be stored in a float variable. A strings b flowlines c memory addresses d directions. Dereferencing a pointer that has not been initialized properly.

In the chapter about arrays brackets were explained as specifying the index of an element of the array. A pointer is used to access the memory location. We saw that pointer values may be assigned to pointers of same type.

Pointers may be assigned which of the following values. A mutability b static typing c. Any integer values c.

A pointer variable can be assigned the address of an ordinary variable assigned the value of another pointer variable provided both pointers point to objects of the same data type. Methods types and code blocks can be defined as unsafe. Assigned a null value subtracted from another provided both pointers print to elements of the same array.

C Variables of all pointer types can be assigned a pointer to void d A pointer to void can be assigned a pointer of any type. In Python a variable may be assigned a value of one type and then later assigned a value of a different type. However pointers may be type cast from one type to another type.
