#include <filesystem>

int main(){
  std::cout << "The current directory is: " 
    << std::filesystem::current_path() << '\n';
  return 0;
}
// g++ -std=c++17 current.cpp && ./a.out

    C

    #include <stdio.h>
#include <unistd.h>
#include <limits.h>

int main() {
  char cwd[PATH_MAX];
  getcwd(cwd, sizeof(cwd));
  printf("The current directory is: %s\n", cwd);
  return 0;
}
// gcc current.c && ./a.out

    Lua

    print("The current directory is: " .. os.getenv("PWD"))
--lua current.lua

    Java

    public class current {
  public static void main(String[] args) {
    System.out.println("The current directory is: " + System.getProperty("user.dir"));
  }
}
// javac current.java && java current

    Bash

    echo "The current directory is: ${PWD}"
# bash current.sh

    JavaScript

    Node.js

    console.log("The current directory is: " + process.cwd() )
// node current.js

    Python

    import os
print("The current directory is: " + os.getcwd())
# python current.py

    PHP

    <?php echo "The current directory is: " . getcwd() . "\n";
# php current.php

    Golang

    package main

import (
  "fmt"
  "os"
)

func main(){
  dir,err := os.Getwd() ; _ = err
  fmt.Println("The current directory is: " + dir)
}
// go build current.go && ./current
