rustHow to increment pointer in Rust

In Rust, you can increment a pointer by using the 'offset' method. This method takes an integer as an argument and adds that number to the pointer's address. For example, if you have a pointer to an integer, you can increment it by one with the following code:

let mut pointer = &mut 5;
pointer = pointer.offset(1);

The output of this code will be the address of the next integer in memory.

The offset method is useful for iterating through a collection of values. For example, if you have an array of integers, you can use the offset method to iterate through each element in the array:

let array = [1, 2, 3, 4, 5];
let mut pointer = &array[0];

for _ in 0..array.len() {
    println!("{}", *pointer);
    pointer = pointer.offset(1);
}

The output of this code will be the values of each element in the array.
