I get two errors with the following code, when compiled in UNIX: PLEASE FIX for good rating!

#include<stdio.h>

#include<fcntl.h>

#include<sys/stat.h>

#include<sys/types.h>

#include<stdlib.h>

int main()

{

int ret = 0;

int fd1 = 0, fd2 = 0;

//Creating main directory named “A4PART1”

ret = mkdir(“./A4PART1”,0766);

if(ret != 0){

fprintf(stderr,”Unable to create directory “A4PART1″n”);

perror(“A4PART1: “);

return -1;

}

//Creating folder1 inside A4PART1

ret = mkdir(“./A4PART1/folder1”,0766);

if(ret != 0){

fprintf(stderr,”Unable to create directory “folder1″n”);

perror(“Folder1: “);

return -1;

}

//Creating folder2 inside A4PART1

ret = mkdir(“./A4PART1/folder2”,0766);

if(ret != 0){

fprintf(stderr,”Unable to create directory “folder2″n”);

perror(“Folder2: “);

return -1;

}

fprintf(stderr,”Unable to create file1.txtn”);

perror(“File1: “);

return -1;

}

}
