rustHow to create pointer in Rust
Creating a pointer in Rust is done by using the &
operator. This operator creates a reference to a value, which can then be used to access the value. For example, to create a pointer to an integer, you can use the following code:
let x = 5;
let x_ptr = &x;
The x_ptr
variable now holds a reference to the x
variable, which can be used to access the value of x
. To access the value of x
through the pointer, you can use the *
operator, like so:
let x = 5;
let x_ptr = &x;
println!("x = {}", *x_ptr);
This will print out x = 5
.
