C++ user input; outputs a shape

Jan 10th, 2006

I need to write a program that inputs an integer and a character, and outputs a symetrical triangle composed of the character that has the interger of new lines. I can only use 'while' loops at this stage of the course, and I know it has to be nested 'while' loops. I can not use 'for/next' loops. I have done this before in VB6, so I am somewhat exasperated that I can not even get past firstbase with this same problem in C++. And I like C++, strangely enough. Ive spent close to 20 hours trying to figure it out and just cant ;0

the display needs to look something like(minus the -'s that i had to use here as a placeholder):

-----$
----$$$
---$$$$$
--$$$$$$$
-$$$$$$$$$

     $
    $$$
   $$$$$
  $$$$$$$
 $$$$$$$$$

I set a variable to the same as the inputed integer and i did
k-- to decrease the space by one every time, but i dont know how i should display more than 1 character per line..

Any suggestions would be greatly appreciated.

#include <iostream.h>

using namespace std;

int main(void)
{
cout<<"enter a integer";
int b;
cin>>b;

cout<<"enter a symbal";
char s;
cin>>s;

int space=b;

int k=1;
for(int i=0; i<b; i++)
{

for(int j=0; j<space; j++)
{
cout<<" ";

}
space--;

for(int m=0; m<k; m++)
{

cout<<s;
}
k=k+2;
cout<<"\n";
}

system("pause");
}
