Could someone help me with my hw here is the problem i have and the code "In this exercise, you create a program that uses two nested loops to display two different patterns of
asterisks: Pattern 1 contains nine rows of asterisks as follows: nine asterisks, eight asterisks, seven
asterisks, six asterisks, five asterisks, four asterisks, three asterisks, two asterisks, and one asterisk . Pattern 2 contains nine rows of asterisks as follows: one asterisk, two asterisks, three
asterisks, four asterisks, five asterisks, six asterisks, seven asterisks, eight asterisks, and nine asterisks."
I have the first part done and i need help to add a "do while" loop

  #include <iostream>
using namespace std;

int main()
{
	int line;
	int numAstericks;

	for (int line = 1;line <= 9; line += 1)
	{
		for (int numAstericks = 1; numAstericks <= line; numAstericks += 1)
			cout << '*';
			//endfor
			cout << endl;
	}


	system("pause");
	return 0;
}

Try this

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

#include <iostream> using namespace std; int main() { for(int i = 9; i >= 0; --i){ for(int ast = 0; ast < i; ast++){ cout << "*"; } cout << endl; } for(int i = 1; i <= 9; ++i){ for(int ast = 1; ast <= i; ast++){ cout << "*"; } cout << endl; } return 0; }

Is there anyway you could do a “do while” loop with it?

[ericM]

yes, but you have to update the incremental value in the for loop so that if it is 0 it turns from -1 to +1.
You go down from 9 to 0 and back form 0 to 9 (do while iterator <=9).
