Thread: help needed

hi guys ...i can,t get to display dis an empty diamond using setw...i,ve written some ov the code..its incomplete..cant get any further..please help! i,ve to submit it in 6 hours.

Code:

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


    #include <iostream.h>
#include <iomanip.h>
int main()
{
	int a,b,c,d,e,x,y,z;
	cout<<"enter no. of rows"<<endl;
	cin>>a;
	
	
	for (x=1; x<=a; x++)
	{
		cout<<setw(x)<<"*"<<endl;
	}

     for (y=10; y>=a; y--)
	 {
		 cout<<setw(y)<<"*"<<endl;
	 }

		return 0;
}

ok i think you will be able to run it now .here is the code and output i get

Code:

            *
              *
                *
                  *
                    *
                            *
                         *
                       *
                     *
                  *

Code:

#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
	int a,x,y;
	cout<<"enter no. of rows"<<endl;
	cin>>a;
	
	
	for (x=1; x<=a; x++)
	{
		cout<<setw(x)<<"*"<<endl;
	}

     for (y=10; y>=a; y--)
	 {
		 cout<<setw(y)<<"*"<<endl;
	 }

		return 0;
}

Notice that other than the first and last lines, you print two asterisks per line. You probably should use variable names that are more descriptive than a, b, c, d, e, x, y, z.

Combine the loops as in to nest them so they work together

I would do that in one loop… something like

Code:

cout << setw(x) << "*" << setw(f) << "*" << endl;

where x is the distance from the left side of the screen to the first * and f is the gap between the stars.

And then just come up with an algorithm that increases the values (x & j) accordingly… and then decreases them

Most C++ compilers don't like “ and ”. " is the proper character.
