rust vector indexing compared to c++

在c++中初始化数组,读写数组,读数组.

#include <vector>
#include <iostream>
using std::vector;
using std::cout;
using std::endl;int main() {vector<int> v={1,2,3,4,5,6};for(int i=0;i<v.size();++i){v[i]+=1;}for(int i=0;i<v.size();++i){cout<<v[i]<<endl;}return 0;
}

在rust中…

use std::ops::IndexMut;
fn main() {let mut v=vec![1,2,3,4,5,6];for i in 0..v.len() {*v.index_mut(i)+=1;}for i in 0..v.len() {println!("{}",v[i]);}
}

markdown好像不支持rust的格式,所以就直接用c++的了.
