New at C++ Need help

I am trying to create a program based on the input of a number to generate a pattern: if the user enters the number 3 the pattern should be -

Code:

---

*** ***
 **  **
 *    *

---

but if I enter the number 4 the pattern would be -

Code:

---

********
***  ***
**    **
*      *

---

Can anyone help out?

Thank-you

two words : For Loop

I can get a pattern to cascade - but I do not understand the while loop

//displays a pattern of asterisks

Code:

---

#include <iostream>
using namespace std;

int main()
{
        //variables
        int outer = 0;
        int inner = 0;

        //perform loops
        outer = 6;
        while (outer > 0)
        {
                inner = 1;
                while (inner <= outer)
                {
                        cout << "*";
                        inner = inner + 1;
                }//end while
                outer = outer - 1;
                cout << endl;
        }//end while

        return 0;
} //end of main function

check this out... its the inverse of what you are looking for but with a little thinking you can switch it around

it uses nested for loops

Code:

---

#include <iostream.h>
#include <conio.h>
int main()
{
 int rows;
 cout<<"How many rows: ";
 cin>>rows;
 cout<<"\n\n\n";
 if(rows == 0)
  {
  cout<<"Thats to little";
  return 0;
  }
  else
  {
 for(int x=0;x<rows;x++)
 {
 
  cout<<"\n";
  for(int y=rows;y>x;y--)
  {
    cout<<" ";
  }
  cout<<"*";
  for(int z=0;z<x;z++)
  {
    cout<<"**";
  }
  cout<<"*";
 }
 }
 getchar();
 return 0;
}

Heres an obfuscated solution for you:

Code:

---

#include<iostream>
#define o cout<<
#define x(X,Y,Z) for(int Z=X;Z-->0;o Y)
#define q x(i,"*",j);
using namespace std;
int main(){
        int s;
        o"Enter a size:";
        cin>>s;
        x(s+1,"\n",i){
        q x(2*(s-i)," ",j);q
        }
}

Think your teacher will accept it?

Nope I don't think he will like it. Here is where I am at now - somewhat closer

It is the while loop I am having problems with.

#include <iostream>
#include <string>
#include <algorithm>

using namespace std;

int main()

{
//variables
string asterik ="";
asterik.assign(3, '*');
int count =1;
int inum = 0;

while (asterik !=0)
{

cout << asterik.assign(inum,'*');
asterik = asterik + "*";
count = count + 1;


cout << asterik +" "+" "+ asterik << endl;

return 0;
} //end of main
