I like the code Prelude wrote.
but I think the main() function should return a value, but it's realy nice.

It's a matter of personal taste. I usually omit the return 0, in favor of code brevity. Both ways are vaild in ISO C++.

use printf() if you must.
I like Prelude's code , but what does the (~n & k) test for?

Code:

for(int i=1; i<=10; i++)
  {
     for(int k=10-i; k>0; k--)
     {
        printf(" ");
     }
   for(j=1; j<=i; j++)
   {
      printf("*");
      printf("\n");
   }
 }

You want 10-i spaces before each line of stars right?
so just print 10-i spaces. Meaning, print a space 10-i times.

Take the printf("\n"); out of the second inside for loop, and put it at the very end of the outside for loop. The rest (arguably) is up to you.

~Inquirer, over and out.

Nested for-loops aren't neccessary:

Code:

for (int i=1;i<=10;++i)
  cout << setw(i) << setfill('*') << "" << endl;

EDIT:

Perhaps this is more what you want:

Code:

for (int i=1;i<=10;++i)
  cout << setw(10-i)<<setfill(' ') << ""<< setw(i) << setfill('*') << "" << endl;
