	### 数组作为参数
	```rust
	fn main(){
	let mut array: [i32 ; 5] = [1,2,3,4,6];
	print_arrays(array);
	println!("元素：{array:?}");
	}
	fn print_arrays(mut array:[i32; 5]) {
	array[0] = 89;
	array[1] = 90;
	array[2] = 91;
	array[3] = 92;
	array[4] = 93;
	println!("元素：{array:?}");
	}
	```
	### 返回数组
	```rust
	fn main(){
	let mut arr:[i32; 5] = [2,4,6,8,10];
	multiply(arr);
	println!("数组是：{:?}", multiply(arr));
	}
	fn multiply (mut arr: [i32 ; 5]) -> [i32 ; 5]{
	arr[2] = 90;
	for mut i in 0..5 {
	arr[i] = arr[i] * arr[2];
	}
	return arr;
	}
	```

@jaywcjlove 我想重新写一下 rust 文档，这部分感觉完全没有用，还有上面的流程控制，应该把模式匹配剥离出来

@jack-zhang-1314 可以的，重新优化排版布局
