is the program valid or not? I am confused.

Question

// 1^2+2^2+3^2+.......+n^2?

#include

int main()
{
    int i,n,result=0;

    printf("Enter n=");

    scanf("%d",&n);

    for(i=1;i<=n;i++)
    {
     printf("%d",i);
     result=result+i*i;

    }
    printf("\nResult=%d\n",result);



    getch();
}
