In cmd.exe, I can execute the command "copy c:\hello.txt c:\hello2.txt" and it worked fine. But in my C program, I ran this piece of code and got the following error:

#include <iostream>

using namespace std;

int main()
{
    system("copy c:\hello.txt c:\hello2.txt");
    system("pause");

    return 0;
}

Output: The system cannot find the file specified.

Anybody know what is going on here?
