Problem Solution:

In this program, we will create a simple vector that contains 5 integer elements then we will find the length of the vector.

Program/Source Code:

The source code to find the length of the vector is given below. The given program is compiled and executed successfully.

// Rust program to find the length of vector

fn main() {
   let mut v = vec![10,20,30,40,50];
 
   println!("Vector elements:\n{:?}", v);
   println!("Length of Vector: {}",v.len());
}

Output:

Vector elements:
[10, 20, 30, 40, 50]
Length of Vector: 5

Explanation:

Here, we created a vector that contains integer elements, and then we found the length of the vector using the len() function and printed the result.
