Submitted by Nidhi, on October 23, 2021

Problem Solution:

In this program, we will create a vector to store the name of countries then we will access the elements of the vector using the index.

Program/Source Code:

The source code to access vector elements using the index is given below. The given program is compiled and executed successfully.

// Rust program to access vector elements 
// using index

fn main() {
   let mut countries = vec!["INDIA","USA"];
   let mut index:usize=0;
   
   countries.push("UK");
   countries.push("CANADA");
   countries.push("ENGLAND");
   
   println!("Countries are: ");
   while index <countries.len()
   {
        println!(" {}", countries[index]);
        index=index+1;
   }
}

Output:

Countries are: 
 INDIA
 USA
 UK
 CANADA
 ENGLAND

Explanation:

Here, we created a vector to store the name of countries, and then we performed a PUSH operation to add the item into the vector. After that, we accessed the elements from the vector and printed them.
