rust vector indexing compared to c++

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.
