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.

  Directory created.
  

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