Donald Knuth , Structured Programming, with go to Statements [1]. In computer science , a pointer is an object in many programming languages that stores a memory address.

C structs and Pointers

Pointer is a variable that stores memory addresses. Unlike normal variables it does not store user given or processed value, instead it stores valid computer memory address.

For beginners pointers can be a bad dream if not practiced well. However, once mastered you can do anything you want to do in C programming language.

In this exercise I will cover most of the pointer related topics from a beginner level. Always feel free to drop your queries and suggestion down below in the comments section.

Pointer allows various magical things to be performed in C. Pointers are more efficient in handling arrays and structures. Pointers are used to return multiple values from a function.

Pointer allows dynamic memory allocation and deallocation creation and deletion of variables at runtime in C. Which undoubtedly is the biggest advantage of pointers. Pointer allows to refer and pass a function as a parameter to functions.

Pointer programming exercises and solutions in C

Pointers are arguably the most difficult feature of C to understand. But, they are one of the features which make C an excellent language. In this article, we will go from the very basics of pointers to their usage with arrays, functions, and structure. Before we get to the definition of pointers, let us understand what happens when we write the following code:. A block of memory is reserved by the compiler to hold an int value. The name of this block is digit and the value stored in this block is

Pointers in C Programming: What is Pointer, Types & Examples

The Pointer in C, is a variable that stores address of another variable. A pointer can also be used to refer to another pointer function. The purpose of pointer is to save memory space and achieve faster execution time.

Pointer to an array :. Pointer to an array is also known as array pointer. We are using the pointer to access the components of the array. We have a pointer ptr that focuses to the 0th component of the array.

This handbook does not try to cover everything under the sun related to C. It focuses on the core of the language, trying to simplify the more complex topics. C is probably the most widely known programming language. It is used as the reference language for computer science courses all over the world, and it's probably the language that people learn the most in school along with Python and Java. C is not just what students use to learn programming.
