Exercise: concatenate file content
Write a function that received the name of two files and returns the content of the two files concatenated in both directions.
e.g. If file 1 contains "cat" and file 2 contains "dog" then return "catdog" and "dogcat"
examples/ownership/concatenate-content-of-files/src/main.rs
fn main() { let res = concatenate("cat.txt", "dog.txt"); println!("{:?} {:?}", res.0, res.1); } fn concatenate(file1: &str, file2: &str) -> (String, String) { let data1 = std::fs::read_to_string(file1).unwrap(); let data1 = data1.trim_end(); let data2 = std::fs::read_to_string(file2).unwrap(); let data2 = data2.trim_end(); (format!("{data1}{data2}"), format!("{data2}{data1}")) }
- TODO: This works, but let's also implement without format!
- TODO: Return Result
