Task #$1.$ Write a C$/$C$++$ program $($myprog l $.$c or myprog l$.$cpp$,$ and its executable named myprog $1)$ to create a few directories as shown below in your current directory $($dirl$,$ dir$2),$ a few files $($filel in current directory, file $10$ in dirl, file$20$ in dir$2,$ and a symbolic$-$link link $1($to link to file$20).$

You are going to create the files and directories in depth$-$first order $($and left to right$).$ That is$,$ dirl will be created first, then file $10,$ and so on$.$ You should create link$1($a softlink to file$20)$ after file$20$ is created.
