How to convert an array of strings to string in Rust

Answer 1

fn convert_array_of_strings_to_string(arr: &[&str]) -> String {
    let mut result = String::new();
    
    for &s in arr {
        result.push_str(s);
        result.push(' ');
    }
    
    result.trim_end().to_string() // Remove the trailing space
}

fn main() {
    let arr = ["rust", "java", "php", "c", "c++", "python"];
    
    let str = convert_array_of_strings_to_string(&arr);
    
    println!("{}", str);
}
