Prime Number - Checker C Program

The below code checks whether the entered number is prime or not.

Logic: Prime numbers are defined as the numbers which are only divisible by one or itself.
This can be checked by dividing the number from 2 to that number.If the number is divisible on any other number other then itself then that number will not be a primer number.Also as 1 is not a prime number,if the user enters 1 print not prime.

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

void main()
{
    int x,y,count=0;
    printf("Enter a number:");
    scanf("%d",&x);
    y=2;
    if(x==1)
        printf("The number %d is not prime",x);
    while(y<=x)
    {
        if(x%y==0)
          count++;
        y++;
    }
    if(count==1)
      printf("The number %d is prime",x);
    else
        printf("The number %d is not prime",x);

    getch();
}
