Different programming languages have their own ways to handle input and output. Here’s a simple look at how three popular languages do it:

1. Python:

   • For getting input, it uses the input() function.
   • To show output, it uses print().
   • Example:
     • Input: name = input("Enter your name: ")
     • Output: print("Hello, " + name)

2. Java:

   • This language uses Scanner to get input.
   • For output, it uses System.out.println().
   • Example:
     • Input: Scanner scanner = new Scanner(System.in);
     • Output: System.out.println("Hello, " + name);

3. JavaScript:

   • It gets input with prompt() and shows output with console.log().
   • Example:
     • Input: var name = prompt("Enter your name: ");
     • Output: console.log("Hello, " + name);

In short, each programming language has its own method for handling input and output. But they all help improve how users interact with programs!
