Hi!
i recently started learning c++, i have been writting code to print Asterisks '*' in shape forms but i just cannot write code to print them in an Equilateral triagle(size depending on the user's input number). i.e. if user inputs 3, it should print:
*
* *
* * *

Help!!!

Please don't respond to code beggars since that will only encourage them to continue to pester us. Don't respond with code unless they can prove that they have made some effort on their part. Thanks.

Also please respond in ANSI C/C++ to avoid learning out bad habits to the newbies. The posted program will not work on any ANSI C/C++ compiler.

Hi,

There is some spaces in the beginning of each line and won't be shown in the posted message, but shown in the reply screen.

#include <iostream>
using namespace std;

#include <stdlib.h> // system()


int main()
{

	int rows_num; // height of triangle (number of rows)
	int i, j; // counters

	cout << "\nPlease enter the height of triangle (number of rows) : ";
	cin  >> rows_num;
	cout << endl;

	int beg_sp = (rows_num-1)*2; // number of beginning spaces
	
	for (i=1; i<=rows_num; i++) // print each row
	{
		for (j=0; j<beg_sp; j++) // print beginning spaces
			cout << ' ';
		for (j=0; j<i; j++) // print stars
			cout << "*   ";
				
		cout << endl; // goto next row

		beg_sp -= 2;
	}
	
	system("pause");
	
	return 0;
}

And this wasn't the first time you did it either.
