In C programming, a pointer is a variable that stores the memory address of another variable. Pointers are powerful and flexible features in C, allowing direct manipulation of memory and providing a way to implement dynamic memory allocation. Here are some key concepts related to pointers: Pointers require careful use to avoid common pitfalls like segmentation faults and undefined behavior. Memory management and pointer arithmetic should be done with caution to ensure the stability and correctness of your programs. Program : #include<stdio.h>#include<conio.h>main(){int a;int *pointer=&a;printf(“Enter the value of a : “);scanf(“%d”,&a);printf(“\nThe value of a is : %d”,a);printf(“\nThe address of a is : %x”,&a);printf(“\nThe value of pointer is : %x”,pointer);printf(“\nThe address of pointer is : %x”,&pointer);getch();} Output :
