Rust Example: Write a program to demonstrate the command line arguments.
Submitted by Nidhi, on November 26, 2021

Problem Solution:

In this program, we will pass arguments at runtime and print them.

Program/Source Code:

The source code to demonstrate the command line arguments is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

// Rust program to demonstrate the 
// command line arguments

fn main(){
   let args = std::env::args(); 
   
   // Print all arguments passed at command line
   println!("Arguments: ");
   for arg in args {
      println!("{}",arg); 
   }
}

Output:

Compile:
$ rustc main.rs

Execute:
$ ./main One Two Three
Arguments: 
./main
One
Two
Three

Explanation:

In the main() function, we printed the command line arguments.
