Pointers is the most powerful tool in c++; it helps the programmer access and manipulates the memory directly. For instance, when a variable is created, the job of the compiler is to do memory allocation to store the value of the variable. And this value is retrieved using the variable nam...

Possible memory leak - pointer to the block exists only in register mel Memory leak - no pointers to the block With leak checking turned on, you get an automatic leak report when the program exits. All leaks including possible leaks are reported at that time. By default, a non-verbose...

to the next node's value if (current->data == current->next->data) { // Update pointers to remove the duplicate node next_next = current->next->next; free(current->next); // Free memory of the duplicate node current->next = next_next; // Update the link to bypass the duplicate...
An array, as we all know, is a collection of elements in a horizontal fashion which are denoted with the help of specific location based parameters known as pointers. Arrays form an integral part of C programming. As you can see in the example specified above, you need to enter the size...
I wanted to do a test and change the default system c:\Program Files path.I can see in my registry that it is given the value %ProgramFiles%. I assumed I could initialize the default value by creating a new system environment variable "ProgramFiles" from the control panel, but when I...
Write a C program to create a copy of a singly linked list with random pointers. Sample Solution:C Code:#include<stdio.h> #include <stdlib.h> // Define a structure for a Node in a singly linked list struct Node { int data; struct Node *next, *random; }; // Function to create ...
By including theheader fileinanother.c, we enable it to call themain() functionfromfirst.c. Thecompilerautomatically connects the two files during thelinking process. Using a Function Pointer to Call main() Another advanced technique tocall main()is by usingfunction pointers. Afunction pointeris...
