Take a look at my program(math problem)

#include <iostream>
#include <conio.h>
#include <conio.c>

#define SHOREHIGH "Welcome to Shore High School!! "

typedef char ZOO:
typedef int USHORT;

USHORT useranswer;

int main()
{
USHORT classrooms(20);
USHORT teachers=2*20;
textcolor(9);
textbackround(7);
cout << SHOREHIGH;
cout << "\nHeres a math problem. There are 20 classrooms, 500 students in the entire school, and 2 teachers per classroom. How many teachers are there in the entire school?";
cin >> useranswer;

if (useranswer==teachers) {
cout << "\nYou're absolutely correct"; }

if (useranswer!=teachers) {
cout << "\nWRONG!! Try again\n"; }

getch();
return 0;
}

Have a better method of making this program?

*Don't use unneccessary #definitions
*Don't use unneccessary typedefs
*Don't use variables when variables aren't needed

Code:

#include <iostream.h>
#include <conio.h>

int main()
{
	short userans;

	cout << "Welcome to Shore High School!!";
	cout << "\nHeres a math problem. There are 20 classrooms, 500 students in the entire \nschool, and 2 teachers per classroom. How many teachers are there in the\nentire school ?"; 
	cin >> userans;

	if (userans == 40) 
		cout << "\nYou're absolutely correct"; 
	else  
		cout << "\nWRONG!! Try again\n"; 

	getch();

	return 0;
}

#include <iostream>
using namespace std;
#include <conio.h>

int main()
{
short userans;

cout << "Welcome to Shore High School!!";
cout << "\nHeres a math problem. There are 20 classrooms, 500 students in the entire \nschool, and 2 teachers per classroom. How many teachers are there in the\nentire school ?";
cin >> userans;
(userans == 40) ? cout<<"U R right" : cout<<"U R wrong";

getch();
return 0;
}

*dont include *.c files
