Hey guys im new here, I have some code I would like you guys to help me fix- this code is for a school assignment and I would like some code experts help.
This code is supposed to tell when you hit the keyboard, and when it is a or s output to the parallel port breadboard. Thanks

// The includes I will need

#include <iostream.h>
#include <conio.h>
#include <math.h>
#include <stdio.h>
#include <time.h>

//Initiating the voids and void main 

void a ();
void s ();

void main ()

{
	if (_kbhit())
	ch= _getch();
	{
		if(ch=='a') void a ();
	}
	{
		if(ch=='s') void s ();
	}
}

// Gives the user a greeting and gives control instructions
{
	printf( "Welcome to the Robot Control Program \n \n") ;
	printf( "Press 'a' to use left motor \n") ;
	printf( "Press 's' to use right motor \n") ;
	printf( "Press 'a' and 's' simultaneously to go forward \n") ;

// Wait loop
{
	while ( (!_kbhit()) );
	{
	}
	while (true);
	{
	
	while (true)
	{
		a();
		s();
		// testing printf("inside loop");
	}
	}
}
}

// 'a' = left motor on code 

void a ()
{
	// testing printf( "we are in 'a' \n") ;
	char ch;
	// testing printf( "we are in 'a' \n") ;
	if (_kbhit()) ch= _getch();
	if(ch=='a') 
	{
	_outp(0x378,2);
	printf( "You have pressed 'a'\n") ;
	// testing cout << "You have pressed 'a' \n";
}
}

// 's' = right motor on code

void s ()
{
	// testing printf( "we are in 's' \n") ;
	char ch;
	// testing printf( "we are in 's' \n") ;
	if (_kbhit()) ch= _getch();
	if(ch=='s') 
	{
	_outp(0x378,3);
	printf( "You have pressed 's' \n") ;
	// testing cout << "You have pressed 's' \n";
}
}

// TEST CODE -   printf("%c",ch);
