Write a C-program to print sum of even or odd numbers based on the n value using single do while loop

#include <stdio.h>
int main() {
    int x=1,n,sum=0;
    printf("Enter n value ");
    scanf("%d",&n);
    do
    {
       
        if(x%2==0 && n%2==0)
        {
            sum=sum+x;
        }
        else if(x%2!=0 && n%2!=0)
        {
            sum=sum+x;
        }
        x++;
    }while(x<=n);
   
    printf("%d sum is %d",n ,sum);
  
    return 0;
}

Enter n value 5

5 sum is 9

Enter n value 6
6 sum is 12
