Solution Review: Concatenate Words Starting With 'c'

Explore how to concatenate words that start with the letter 'c' in a Rust string by applying split, starts_with, and pop methods. Learn to process and manipulate string data effectively using loops and conditionals to build a new string. This lesson solidifies your skills in Rust string handling before moving to vectors.

We'll cover the following...

Solution:

Rust 1.40.0
fn test(my_str:String)-> String {

    let mut my_updated_string = "".to_string(); 

    for word in my_str.split(" "){

         if word.starts_with("c"){

             my_updated_string.push_str(word);

             my_updated_string.push(' ');

         }

        }

    my_updated_string.pop();

    my_updated_string

}

fn main(){

    let  my_str= "This is a comprehensive course in Rust programming language on Educative. Read it with full concentration to grasp the content of the course";

    println!("Original String: {}", my_str);

    let updated_string = test(my_str.to_string());

    println!("Updated String: {}", updated_string);

}
