Pointers in C Program with Source Code

Pointers in C Program; A variable that stores the address of another variable is known as a pointer.

In contrast to other variables that retain values of a certain type, a pointer variable holds the address of a variable.

An integer variable, for example, holds (or saves) an integer value, whereas an integer pointer keeps the address of an integer variable.

We have included downloadable zip file in C at the end of the program so that you may run the following codes.

Example Program

 #include<stdio.h>
int main(){
int number=50;
int *p;
p=&number;//stores the address of number variable
printf("Address of p variable is %x \n",p); // p contains the address of the number therefore printing p gives the address of number.
printf("Value of p variable is %d \n",*p); // As we know that * is used to dereference a pointer therefore if we print *p, we will get the value stored at the address contained by p.
return 0;
}

Output:

Address of p variable is 61fe14
Value of p variable is 50

What is the importance pointers in c programming?

Pointers are a fast way to access the elements of an array structure. Pointers are utilized in both dynamic memory allocation and deallocation. In Addition, pointers are used to create complicated data structures like linked lists, graphs, and trees.

What is the use of programs using pointers in c?

pointers in c programming with examples employs pointers to build dynamic data structures, which are made up of memory blocks allocated from the heap at run-time. they are used in C to handle variable parameters provided to functions. In C, pointers provide an alternative method of accessing information contained in arrays.

What is the distinction between an array and a pointers in c programming language?

In C, arrays are used to store elements of the same type, whereas pointers are address variables that hold the address of a variable. Now, array variables have addresses that can be directed by pointers, and arrays may be traversed using pointers.

About the Project

pointers in c programming with examples can provide dynamic memory management thanks to pointers. Pointers shorten and complicate programming.

Moreover, Pointers accelerate execution and thereby reduce program execution time. They are a useful tool for handling dynamic data structures such as structures, unions, linked lists, and so on.

The Program below includes all of the essential and necessary components that first-, second-, and third-year IT students can use for college assignments.

The project was totally written in C and edited using the Codeblocks editor.
