Haskell Program to print system information

Program

import System.Info
main = do
 putStrLn ("Operating System: " ++ os)
 putStrLn ("Architecture: " ++ arch)
 putStrLn ("Compiler Name: " ++ compilerName)
 putStrLn ("Compiler Version: " ++ compilerVersion)

This Haskell program retrieves and displays system-related details such as the operating system, architecture, compiler name, and compiler version.

1. import System.Info

   • Imports the System.Info module, which provides system-related information.

2. putStrLn ("Operating System: " ++ os)

   • Prints the name of the operating system using the os variable.

3. putStrLn ("Architecture: " ++ arch)

   • Prints the system architecture (e.g., "x86_64" or "arm").

4. putStrLn ("Compiler Name: " ++ compilerName)

   • Displays the name of the Haskell compiler used.

5. putStrLn ("Compiler Version: " ++ compilerVersion)

   • Displays the version of the Haskell compiler.

Key Takeaways

• The System.Info module provides system-related details.
• The program prints OS, architecture, and compiler details using predefined variables (os, arch, compilerName, compilerVersion).
• Useful for debugging or gathering system configuration details.
