#include <iostream>
#include <string>

int main() {
  unsigned int initialNumberOfStars = 0;
  std::cin >> initialNumberOfStars;
  for ( int i = initialNumberOfStars; i > 0; --i ) {
    std::string stars( i, '*' );
    std::cout << stars << std::endl;
  }
}

Enjoy!

#include <iostream>
#include <iomanip>

int main()
{
	while ( true )
	{
		std::cout << "Enter a non-negative number (0 - exit): ";

		size_t n = 0;
		std::cin >> n;

		if ( !n ) break;

		std::cout << std::endl;
		std::cout << std::setfill( '*' );

		while ( n ) std::cout << std::setw( n-- + 1 ) << '\n';

		std::cout << std::endl;
	}
}

Also try the following

#include <iostream>
#include <iomanip>

int main()
{
	while ( true )
	{
		std::cout << "Enter a non-negative number (0 - exit): ";

		size_t n = 0;
		std::cin >> n;

		if ( !n ) break;

		std::cout << std::endl;
		std::cout << std::setfill( '*' );

		size_t i = 0;
		while ( i < n ) std::cout << std::setw( i++ + 1 ) << '\n';
		while ( i ) std::cout << std::setw( i-- + 1 ) << '\n';

		std::cout << std::endl;
	}
}

Another:

#include <iostream>
#include <iomanip>

void print_stars( const unsigned int amount )
{
    if ( amount == 0 ) return;    
    std::cout << std::setfill('*') << std::setw( amount + 1 ) << '\n';
    print_stars( amount - 1 );
}

int main(void)
{
    print_stars(10);
    return 0;
}
