spaces

I have a problem for school , I could really use some help on, I needed to make a loop that would print a block of asteriks 10 x 10, then I need to break the block down into a triangle like so

Code:

---

int main(int argc, char *argv[])
{
 

        { 

        int x;
        int y;
        for ( x=0; x<=9; x++)
        {

                for (y=x-0;y <=9; ++y){
                printf("*");                  }


            printf("\n");
        }
        }
    return 0;
}

---

my problem is the next step I need a loop that will print

Code:

---

      **********
        *********
          ********
            *******
              ******
                *****
                  ****
                    ***
                      **
                      *

I realized the only way is to add spaces, problem is I dont know how to add spaces to a loop yet, they should line up and be squared, but I cant get them to stay lined up when I post this.
thx for any help,
btw, notice i used the code box this time lol

Code:

---

for(i=0, j=0;i<10;i++) {
  for(; j<i;j++)  //print the leading spaces for each row
    printf(" ");
 
  //now add your code to print out the number of stars, here

  //now print your \n char
  //and loop back for the next row
}

I noticed the code tags - will wonders never cease?? :p :p

The exact same way that you're adding asterisks: printf(" "); You just need to write a quick loop that on each iterations, writes the correct number of spaces and the the correct number of asterisks - that should be simple linear math.

thx again guys!
sometimes I think I make this a lot harder than it really is
