Rust program to iterate the items of the vector using the 'for' loop

Rust | Vector Example: Write a program to iterate the items of the vector using the 'for' loop.
Last Updated : October 24, 2021

Problem Statement

In this program, we will create a vector of string elements using the new() method then we will add items into the created vector using the push() method and access vector elements using the "for" loop.

Program/Source Code

The source code to iterate the items of the vector using the "for" loop is given below. The given program is compiled and executed successfully.

// Rust program to iterate the items 
// of vector using "for" loop

fn main() {
    let mut countries: Vec<&str> = Vec::new();
    let mut index:usize=0;
   
    countries.push("INDIA");
    countries.push("USA");
    countries.push("UK");
    countries.push("CANADA");
    countries.push("ENGLAND");
   
    println!("Countries are: ");
    for item in countries  
    {  
        println!("  {} ",item);  
    }  
}

Output

Countries are: 
  INDIA 
  USA 
  UK 
  CANADA 
  ENGLAND

Explanation

Here, we created a vector using the new() method to store the name of countries. Then we added items into created vector. After that, we iterate vector elements using the "for" loop and printed them.
