C Program to Check Prime Number By Creating a Function

#include<stdio.h>
int checkPrime(int number)
{
  int count = 0;
  for(int i=2; i<=number/2; i++)
  {
     if(number%i == 0)
     {
       count=1;
       break;
     }
  }
  if(number == 1) count = 1;
  return count;
}
int main()
{
  int number ;
  printf("Enter number: ");
  scanf("%d",&number);
  if(checkPrime(number) == 0)
  printf("%d is a prime number.", number);
  else
  printf("%d is not a prime number.", number);
  return 0;
}
