Print Address Code The “*” (asterisk) operator is a pointer to a variable. Compare Address’ Code Using pointers allows us to pass variables into functions, and then manipulate the values of these variables i
The actual bit pattern used for a null pointer may or may not evaluate to zero since it depends on the specific system on which the code is developed. To make the source code compatible between various compilers on various systems, a macro is used to represent a null pointer. That macro ...
A stack pointer is a small register that stores the memory address of the last dataelementadded to the stack or, in some cases, the first available address in the stack. Astackis a specialized buffer that is used by a program's functions to store data such as parameters, localvariablesand...
mouse acceleration is a feature that adjusts the movement of the mouse pointer based on the speed at which you move the physical mouse. with mouse acceleration enabled, the pointer moves a greater distance on the screen when you move the mouse quickly and a shorter distance when you move it...
A fork bomb is a denial-of-service attack. A tiny piece of code causes a process to replicate, and each time, the new instance of the program further depletes available system resources. When the attack pushes a server to the limit, it crashes. ...
What is a program counter (PC)? The program counter, also known as the instruction pointer or simply PC, is a fundamental component of a computer's central processing unit (CPU). It is a special register that keeps track of the memory address of the next instruction to be executed in a...
While the main purpose of the Domain Name System is to point domains to IP addresses, a PTR record works in the opposite way - it associates an IP with a
Converting text to ASCII code in Windows There is more than one way to display text as ASCII codes in Windows. To use the WindowsPowerShell commandFormat-Hex to display ASCII encoding for a text file, take these steps: Open the Windows PowerShell application.Click on the search box in the...
In practice, what is passed is a pointer to theOuterprocedure’s stack frame. Now, if the containing function or precedure happens itself to be nested, then you can use the parent’s frame to access the local variables of the grandparent. ...
pointer that calls the virtual node turns to shellcode. Another operation M→tail→head=M→head during the removal from the linked list can also be used to implement attacks. Heap spraying attack: Heap spraying is a technique used by the attacker in exploits to enable the execution of ...
