Even-Odd Checker C program

The below code checks whether a number is even or odd using switch structure.

Logic: 
If a number is divided by 2 and the remainder is zero then that number is an even number.

Code:
#include <stdio.h>
#include <conio.h>

void main()
{
    int x;
    char ch;

        printf("Even-Odd checker\nEnter a number:");
        scanf("%d",&x);

        switch(x%2)
        {
        case 0:
            printf("The number is even");
            break;
        case 1:
            printf("The number is odd");

        }
        printf("\n\n(*_*) Would you like to run again...(Y/N)");
        scanf(" %c",&ch);
        if(ch=='Y'||ch=='y')
            {
                system("cls");
                main();
            }
        printf("\npress any key to continue");
        getch();
}
