Pointers in c++

Question

Can anyone simplify pointers to me? Its really hard to understand.

Answer 1

pointers help to store address of another variable =>
int *p;
p=&5;
cout<<p; // output is address of 5
//not value
cout<<*p; // output is 5-value
//itself
try yourself))

Answer 2

try like this
int *p, a=5;
p=&a;

Answer 3

Pointers are used in C++ program to access the memory and manipulate them.
Each variable you create in your program is assigned a location in the computer's memory.
C++ gives you the power to manipulate the data in the computer's memory directly. You can assign and de-assign any space in the memory as you wish. This is done using Pointer variables.
