Quiz on Pointers in C Programming

What is a pointer in C programming?

• A function that compares elements in an array

• A data type that stores multiple values of the same type

• A variable that holds the address of an object

• A keyword used to define classes

How is the arrow operator used with pointers in C?

• To access members of a structure pointed to by the pointer

• To indicate multiplication

• To define a new variable

• To perform logical operations

What is the primary difference between an array and a pointer in C?

• An array is used for comparison operations, while a pointer is used for arithmetic operations

• An array is a contiguous chunk of memory, while a pointer holds the address of the first value

• An array is a data type, while a pointer is a keyword

• An array holds the address of an object, while a pointer stores multiple values

What does pointer arithmetic involve in C programming?

• Creating new data types

• Sorting elements in an array

• Performing mathematical calculations

• Manipulating memory addresses directly

What is a character pointer in C used for?

• To store the address of a function

• To perform logical operations

• To define classes

• To point to the first byte of a string in memory

What is the purpose of a void pointer in C?

• To store the memory address with no type information

• To define generic data types

• To point to the first value in an array

• To compare elements in a data structure

How are function pointers used in C programming?

• To define classes and objects

• To store multiple values of the same type

• To access members of a structure

• To dynamically change which function is called in a program

What is the difference between an uninitialized pointer and a null pointer?

• An uninitialized pointer is set to zero, while a null pointer is set to a random value

• An uninitialized pointer is used for arithmetic operations, while a null pointer is used for comparison operations

• An uninitialized pointer points to a function, while a null pointer points to an object

• An uninitialized pointer has a random value, while a null pointer does not point to any object

What is the concept of indirection in relation to pointers?

• Pointers hold actual values or types

• Pointers are used for comparison operations

• Pointers point to the location of memory where values are stored

• Pointers are used for logical operations

Why are pointers considered powerful in C programming?

• Because they are used for defining classes

• Because they allow access and use of objects without needing a whole copy

• Because they are used for sorting elements in an array

• Because they can store multiple values of the same type
