139. What is the size of a pointer? 4 bytes 8 bytes 16 bytes Vary from processor to processor Answer:D) Vary from processor to processor Explanation: The size of the pointer is varied from processor to processors like 16-bit, 32-bit, and 64-bit processors. ...
Actually a pointer is just a address holder so its size is always that of an int data type,what ever may be the type of pointer.In a 16-bit compiler,its 2 bytes and in 32-bit compiler,its 4 bytes(ie depeds on sizeof(int)) Was this answer useful? Yes Replyshivam...
SIZE; i++) { /* for indices 1 through 5, set a pointer to point to a corresponding integer: */ array_of_pointers[i] = &array_of_integers[i]; } for ( i = 0; i < ARRAY_SIZE; i++) { /* print the values of the integers pointed to by the pointers: */ printf("array_of...
what is a mouse pointer? a mouse pointer is a small, graphical symbol or icon that appears on your computer screen and moves in response to your physical mouse movements. it serves as a visual representation of the position and actions of your mouse. how does the mouse pointer work? the ...
format string is customized by users, attackerscanforge the format string and use the features of the *printf() series functions to snoop on the content in the stack space. Ultra-long input can cause conventional buffer overflow, or it can use %n to overwrite the pointer or return address....
Pointer Subterfuge This type of buffer overflow involves manipulating pointers to redirect the program’s execution flow. By overwriting function pointers or other critical pointers, an attacker can control which code is executed or redirect the flow to their malicious code. Return-oriented Programming ...
a stack pointer is a type of pointer used to keep track of the top of the stack. it points to the place in memory where the top element of the stack is stored. when an element is pushed onto the stack, the stack pointer is incremented (or moved forward), and when an element is ...
if I understand it correctly, a zero-size access is invalid if the pointer points to a deallocated memory, correct? I'm assuming that's because of provenance. This used to be the case but we decided to change it and allow more code. Seerust-lang/rust#117945. Once that is fully imple...

ICMP is an error reporting mechanism. If an error occurs during packet processing, ICMP reports the error to the source device of the packet. ICMP neither corrects the error nor notifies the intermediate network devices of the error. An ICMP message is encapsulated as a part of an IP datagram...
