Write a program to implement following UNIX commands (any two options) 1) mkdir <pathname> It creates new directory for a given path 2) cd <pathname> It changes directory to a given paths 3) rmdir <pathname> It deletes removes directory for a given path

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
char *buff,*t1,*t2,*t3,ch;

main()
{
   int n;
   clrscr();
   while(1)
   {
printf("myshell$");
fflush(stdin);
t1=(char *)malloc(80);
t2=(char *)malloc(80);

buff=(char *)malloc(80);
fgets(buff,80,stdin);
n=sscanf(buff,"%s %s %s",t1,t2);
if(strcmp(t1,"exit")==0)
exit(0);

if(strcmp(t1,"mkdir")==0)
{
  if(mkdir(t2)==-1)
   perror(" ");
  else
  {
   mkdir(t2);
     mkdir();

  }
}


else if(strcmp(t1,"rmdir")==0)

 else
  {

  }
}
