Problem: Write a C/C++ program to create a folder in a specific directory path.

This task can be accomplished by using the mkdir() function. Directories are created with this function. (There is also a shell command mkdir which does the same thing). The mkdir() function creates a new, empty directory with name filename.

// mkdir() function
int mkdir (char *filename)

Note: A return value of 0 indicates successful completion, and -1 indicates failure.

• Program to create a directory in Windows using Turbo C compiler:
  
  

  
  
  

  // C program to create a folder #include <conio.h> #include <sys/types.h> #include <sys/stat.h> #include <unistd.h> #include <stdio.h> #include <stdlib.h>    void main() {     int check;     char* dirname = "geeskforgeeks";     clrscr();        check = mkdir(dirname,0777);        // check if directory is created or not     if (!check)         printf("Directory created\n");     else {         printf("Unable to create directory\n");         exit(1);     }        getch();        system("dir");     getch(); }

  Output:

  Directory created.
  a.out  geeskforgeeks  main.c 
  

• Program to create a directory in Linux/Unix using GCC/G++ compiler:
  
  

  
  
  

  // C++ program to create a directory in Linux #include <bits/stdc++.h> #include <iostream> #include <sys/stat.h> #include <sys/types.h> using namespace std;    int main()    {        // Creating a directory     if (mkdir("geeksforgeeks", 0777) == -1)         cerr << "Error :  " << strerror(errno) << endl;        else         cout << "Directory created"; }

  Output:

  
  
  
  

  Directory created.
  
  

Note: Above source codes would not run on online IDEs as the program requires the directory path in the system itself.
