Thread: wht bout a triangle

how to make a Triangle
i want somthg like this

Code:

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

plz help me

ok so this is wht i did so far but then how do i account for the spaces??

Code:

#include <iostream>

using namespace std;

int main ()
{
	int n, r, c;
	char s;
	cout << "Enter # of rows: " << flush;
	cin  >> n;
	cout << "Enter a character: " << flush;
	cin  >> s;

	r = 1;
	
	while (r <= n)
	{
		
		c= 1;
		while (c <= r)
		{
			cout << space;
			cout << s;
			c++;
		}
		r++;
		cout << endl;
	}
	return 0;
}

o the

Code:

cout << space;

shouldnt be there!!

In C/C++ space is a char, ' '. To make it more visual substitue a # for every space you need to use.

depending on what type of triangle you are trying to build. When you describe in English how to solve one of the above for max of 7 *s, then you can try to change the English into C/C++. The biggest problem in writing code is often how to solve the problem without using code. The essential C/C++ stuff can be done with the top triangle. The last one requires a little more thought, but it's basically the same problem.

Hint: let the first loop control the line and the second loop the number of # and * to print. Develop a method to relate the line number, number of #, and number of * as needed to solve each triangle, building on what you did for each of the preceding triangles.
