The pattern contains N rows and each row contains N-x + 1 columns (where x is the current row number). So to print hollow inverted right triangle star patterns in C inner loop print star for first or last column or last row otherwise print space.

for(y=x; y<= rows; ++y)
{
    if((x==1) || (y==x) || (y==rows))
    {
        //Print star
        printf("*");
    }
    else
    {
        //Print space
        printf(" ");
    }
}
