Create Directory or Folder with C/C++ Program

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.

    code

    // C program to create a folder
    #include <conio.h>
    #include <dir.h>
    #include <process.h>
    #include <stdio.h>
      
    void main()
    {
        int check;
        char* dirname = "geeskforgeeks";
        clrscr();
      
        check = mkdir(dirname);
      
        // 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/p");
        getch();
    }

    #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.
