A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before you can use it to store any variable address.
There are few important operations, which we will do with the help of pointers very frequently. (a) we define a pointer variable (b) assign the address of a variable to a pointer and (c) finally access the value at the address available in the pointer variable. This is done by using unary operator * that returns the value of the variable located at the address specified by its operand.
This presentation, created by Syed Faiz ul Hassan, explores the profound influence of media on public perception and behavior. It delves into the evolution of media from oral traditions to modern digital and social media platforms. Key topics include the role of media in information propagation, socialization, crisis awareness, globalization, and education. The presentation also examines media influence through agenda setting, propaganda, and manipulative techniques used by advertisers and marketers. Furthermore, it highlights the impact of surveillance enabled by media technologies on personal behavior and preferences. Through this comprehensive overview, the presentation aims to shed light on how media shapes collective consciousness and public opinion.

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

2. WHAT IS A POINTER ?
in c language pointer is a variable that
stores the address of another variable.
the pointer is used to allocate memory
dynamically i.e. at run time.
the pointer variable might be belonging to
any of the data type such as int , float,
double , char etc.
3. DECLARATION
a pointer in c language can be declared
using *(asterisk symbol) it is also
known as indirection pointer used to
dereference a pointer.
int*p; // pointer to int
char*p; //pointer to char
4. FOR EXAMPLE:
Int *p;
It declares the variable p as
A pointerVariable that points
To an intiger data type.
5. TYPES OF POINTER
1. Null pointer
2. Wild pointer
3. Near pointer
4. Far pointer
5. Huge pointer
6. Generic Or void pointer
6. ADVANTAGES OF POINTER
• Pointers reduce the length and complexity of
a program.
• pointers increase execution speed.
• we can return multiple values from a function using
pointers.
• pointers are more efficient in handling the data tables.
7. EXAMPLE
#include<stdio.h>
int main(){
int number=50;
int *p;
p=&number;
printf("Address of p variable is %x n",p);
printf("Value of p variable is %d n",*p);
return 0;
}
Output
Address of p variable is fff4
Value of p variable is 50
