SYSTEM function

[iTq4jE8b]

My friend have a problem and he can't access CMD, so I wrote this to help him
It's working pretty fine, my problem is that I can't pass the command "cd .." or navigate to any directory.
Is there any solution for that?
Thanks in advance

#include<iostream.h>
#include<windows.h>
int main(){
	char command[100];
	while (1){
		cout<<"Enter a command:\n";
		cin.getline(command,100, '\n');
		system(command);
		cout <<"\nDone!\n";
	}
	return 0;
}

Yea It probably is a virus, Go into system 32 and check if all the cmd commands are all there.
If not, Do a windows repair.
especially cmd.exe Also look in your Registry ( doubt anything in there) , and services.

change #include <iostream.h>
to just
#include <iostream>

Thank you guys, but I'm not trying to fix anything he has, and it's not a virus
I've tried it on many computers, I get the same.
I don't want the cmd.exe to work again, all I want is the "cd" command to work and be able to navigate.
