### can you helpp me plz

Questions:
1. Write a program that reads two integer numbers and calculates the result according to the option chosen from the following menu:
***************************
1- Define large.
2- One multiple of other.
3- Exit.
***************************

Description of the options:
- Option 1: compare both numbers and print out a message with the larger one.
- Option 2: check if the first number is multiple of the second and vice versa.
- Option 3: ends the program. One statement will be in this case which is exit(0).
- If the user enters a wrong option, an error message should be displayed.
Hint: Use switch statements.

______________________________________
Please enter two integers: 10 20

***************************
1- Define large.
2- One multiple of other.
3- Exit.
***************************

20 is larger than 10

my solve ::::

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

int main()
{
int x,y,choice;
while(1)
{
system("cls");
cout<<"Please enter two integers: \n "
<<"\tenter the first intiger : ";
cin>>x;
cout<< "\tenter the second intiger : ";
cin>>y;
cout<< "\n\n(1)-Define large."
<< "\n(2)-One multiple of other."
<< "\n(3)-Exit." ;
cin>>choice;
switch (choice)
{
case 1: if(x != y)
if (x>y)
cout<<x<<" is larger than "<<y<<endl;
else
cout<<y<<" is larger than "<<x<<endl;
else cout<<y<<" == " <<x;
getch();

break;
case 2:
if (x%y == 0)
cout<<x<<" is a multiple of "<<y<<endl;
else
if (y%x == 0)
cout<<y<<" is a multiple of "<<x<<endl;
else cout<<x<<" is not a multiple of " <<y<<" and vice versa";
getch();
break;
case 3:
cout<<"Thank you !! and Goodbye.."<<endl;
exit(o);
break;
default:
cout<<"sorry!!..you have to chose a number from 1 to 3 "<<endl; getch();
}
}
return 0;
};

but when i do run tell me i have some erroe
can you help me plz ^_^

other solve but agine i have error
#include <iostream>

cin>>x>>y;
cin>>choice;

switch (choice)
{
case 1:
if (x>y)
cout<<x<<" is larger than "<<y<<endl;
else
cout<<y<<" is larger than "<<x<<endl;
break;
case 2:
if (x== 2*y)
cout<<x<<" is a multiple of "<<y<<endl;
else
if (y== 2*x)
cout<<y<<" is a multiple of "<<x<<endl;
break;
case 3:
cout<<"Thank you !! and Goodbye.."<<endl;
exit(o);
break;
default:
cout<<"sorry!!..you have chosen a wrong option.. Goodbye!!"<<endl;
