    > I'm calling the cd section of the cmd to change the directory in which the 'ls' displays.
    No you're not.
    You're changing the current directory in the process that system() spawns.
    You're NOT changing the current directory in this process.
    http://man7.org/linu...n2/chdir.2.html


    > Please explain more about 'current directory' being global for the entire process, not local to the stack frame.
    void foo ( ) {
      chdir("foo");
    }
    void bar ( ) {
      chdir("bar");
      foo();
      // now current dir is "foo", even though
      // we've returned from foo()
    }

    But still wide awake enough to spam the forums with your trivial question.

    > 19 system(cmd.c_str());//executing the previous string
    You CANNOT do this!
    All you're doing here is creating another process (read the manual on what system() does), and in that process you change directory.
    The current directory within your process remains as it was.

    If you want to change the directory in this process, use the chdir() function.

    Also note that the 'current directory' is global for your entire process, not local to a functions stack frame.
