How to get address of pointer in Rust

// plain

In Rust, you can get the address of a pointer by using the & operator. For example, if you have a pointer ptr pointing to a value val, you can get the address of ptr by using &ptr. The ## Code example below shows how to get the address of a pointer:

let val = 10;
let ptr = &val;
let address = &ptr;
println!("The address of the pointer is {:p}", address);

The output of the code above will be:

The address of the pointer is 0x7ffc9f9f9f90

The & operator is used to get the address of a pointer. In this example, ptr is a pointer pointing to the value val, and address is a pointer pointing to the address of ptr. The println! macro is used to print the address of ptr to the console. The {:p} format specifier is used to print the address in a hexadecimal format.
