Access Array Elements Using Pointers #include <stdio.h> int main() { int data[5]; printf("Enter elements: "); for (int i = 0; i < 5; ++i) scanf("%d", data + i); printf("You entered: \n"); for (int i = 0; i < 5; ++i) printf("%d\n", *(data + i)); return...
Pointers are powerful features of C and C++ programming. Before we learn pointers, let's learn about addresses in C programming. Address in C If you have a variablevarin your program,&varwill give you its address in the memory. We have used address numerous times while using thescanf()func...
Because PP also has its address, so we can create as many pointers to pointers as we need. char***ppp; ppp=&pp;printf("\n This is the content of ***ppp: %c ", ***ppp); Using a pointers to pointers can be very useful. For example: If you want to have a list of characters...
In this C Programming example, we will discuss how to swap two numbers using the pointers in C and also discuss the execution and pseudocode in detail.
Title is: Understanding c pointers Because a pointer is essentially an integer, you can print the value of a pointer from your program if you want, thus seeing the location in memory to which it points. This is useful mainly for debugging, and is a feature debuggers offer. The...
Printing pointers We can print a pointer value using printf() function with the %p format specifier. Following program prints out some pointer values: Code: #include <stdio.h> #include <stdlib.h> int n = 0; /* a global variable*/ ...
while the operating system manages the pointer *p. Because the OS manages *p, the block pointed to by *p (**p) can be moved, and *p can be changed to reflect the move without affecting the program using p. Pointers to pointers are also frequently used in C to handle pointer parameters ...

assigned to the pointer.It is possible to assign address of single variable or that of an array or the address of a structure etc to a pointer variable.This capability makes pointers the most powerful tool in C programming. We can literally play with the memory of a system using pointers....
