Pointers - C Programming Questions and Answers

Coding interview questions certainly come out of the box especially during the placement drives. But, that does not mean that you cannot tackle those questions within the given time limit!

From Data Structure and Algorithms to Pointers, coding interview questions definitely come with a twist that one cannot predict until they have appeared for the tests themselves.

With that said, the Coding Interviews are also very versatile when it comes to picking a programming language of your choice for writing the codes.

If you are a C developer, then it is vital to understand and tackle questions on Pointers in C in order to shine through during your coding interview.

In effect to that, make sure to read this blog till the end to learn the concept of Pointers in C programming.

Learn about Pointers in C programming

Pointers are a fundamental part of computer programming. They can be used to store a memory address of another variable, which allows for indirect addressing.

The pointer is then used to access the data. Pointers are especially useful when dealing with variables that are dynamic and must be accessed in many different places.

The only issue with pointers is that they can be confusing to beginners, but they are an important tool that can be used to create many different programs.

With effect to that, we would definitely recommend practicing questions based on Pointers if you are interested in landing jobs in some of the highly reputed Multinational Tech Corporates such as Amazon, Google or Microsoft.

Text Based Questions on Pointers

In the following section you will find important text based questions on C programming that are important from an interview perspective.

Q. How would you define Pointers in C programming?

Ans. Pointers are similar to variables, the only difference is that pointers are used for storing the address of a specific memory location whereas variables store values. On that note, we can say that pointers are used to refer to locations in memory.

If you use a pointer in order to save an address in memory, you can also use indirection techniques to get the position of the pointer from the address.

Q. What do you mean by NULL Pointer?

Ans. In C standard, an integer's constant expression along with a value of 0 or a similar expression made to express a type of void x is commonly referred to as a constant null pointer. When a constant NULL pointer is converted into a pointer type, the resultant pointer is called his NULL pointer.

Q. Define generic pointers or void in C programming.

Ans. A generic pointer is defined as the void pointer which has no associated data type. It stores the address of any type of object or cast.

According to the C standard, pointers to void must have the same appearance and alignment requirements as pointers to character types.

A void pointer declaration is similar to a regular pointer, the difference being the use of the void keyword instead of the data type. Read Full Article....
