Adding a Task

Part of the Logic & Flow section of Coddy's Rust journey — lesson 16 of 66.

Challenge

Easy

You will receive two inputs: first, a comma-separated list of existing tasks, and second, a new task to add. Read both inputs, create a vector from the existing tasks, add the new task to the vector, and print the updated task list.

Requirements:

Read the first input containing comma-separated task descriptions (e.g., Buy groceries,Call dentist)
Split the string by commas to get individual tasks
Create a mutable vector and add each existing task to it
Read the second input containing the new task to add
Use .push() to add the new task to the vector
Print the total number of tasks in the format: Total tasks: X
Print each task on a separate line in the format: Task: [task description]

Input:

First line: Comma-separated task descriptions (e.g., Buy groceries,Call dentist)
Second line: A new task to add (e.g., Finish homework)

Output:

First line: Total tasks: X where X is the total number of tasks after adding the new one
Following lines: Each task printed as Task: [task description]

Try it yourself

use std::io;

fn main() {
    // Read the first input (comma-separated tasks)
    let mut existing_tasks = String::new();
    io::stdin().read_line(&mut existing_tasks).expect("Failed to read line");
    let existing_tasks = existing_tasks.trim();
    
    // Read the second input (new task to add)
    let mut new_task = String::new();
    io::stdin().read_line(&mut new_task).expect("Failed to read line");
    let new_task = new_task.trim();
    
    // TODO: Write your code below
    // Split existing_tasks by commas and create a mutable vector
    // Add the new task to the vector
    // Print the total number of tasks
    // Print each task in the required format
