rustHow to do pointer write in Rust

In Rust, pointers are used to refer to a memory location and can be dereferenced to access the data stored at that location. To write a pointer in Rust, you need to use the asterisk (*) operator. For example, to declare a pointer to an integer, you would write:

let x = 5;
let ptr = &x;

Here, ptr is a pointer to the integer x. To dereference the pointer, you can use the asterisk operator:

let y = *ptr;

This will assign the value of x to y.

Output example:

let x = 5;
let ptr = &x;
let y = *ptr;

Explanation

In the first line, we declare an integer x with the value of 5. In the second line, we declare a pointer ptr to the integer x using the & operator. Finally, in the third line, we dereference the pointer ptr using the asterisk operator * and assign the value of x to y.
