#include<iostream>
using namespace std;


#include <stdio.h>
#include <conio.h>
#include <dos.h>

#include <windows.h>

void gotoxy(int xpos, int ypos)
{
COORD scrn;

HANDLE hOuput = GetStdHandle(STD_OUTPUT_HANDLE);

scrn.X = xpos; scrn.Y = ypos;

SetConsoleCursorPosition(hOuput,scrn);
}


int main (void)
{

int row=0,col=0;
cout<<"press any Arrow key or enter: ";
while(1)
{
if(kbhit())
{
char c = getch();



if(c==-32)
{
c = getch();

if(c==80) // Downward
{
cout<<"Downward";
}
else if(c==75) // Left
{
cout<<"Left";
}
else if(c==77) // Up
{
cout<<"Right";
}
else if(c== 72) // Right
{
cout<<"Up";
}

}
else if(c==13)
{
cout<<"Enter";
}
else if(c==32)
{
cout<<"Space";
}
else
{
cout<<c;
}


row++;
gotoxy(0+col,row+0);

cout<<"press any Arrow key or enter: ";

}
}
return 0;
}

This is in c++.Just do a small change to transfer it into C and then run,you will get your answer.Or simply run as c++ project
