Print a Diamond

Jul 5th, 2004

My assignment is to write a program that produces a diamond when the user inputs an integer, if the integer is even it should be increased to the next odd number.

if the number is 7, it should print:

___*
__***
_*****
*******
_*****
__***
___*

(Without the underscores.)

So far I am able to produce the following output with the code I have written:

Enter number: 7
3

*
**
***
Press any key to continue

#include <iostream>
using std::cout;
using std::cin;
using std::endl;

int main()
{

int n;

cout<<"Enter number: ";
cin>>n;

cout<<n/2<<endl<<endl;

for(int i=0; i<=n/2; i++){
cout<<" ";

for(int st=1; st<=i; st++)
{
cout<<"*";
}
cout<<endl;
}

return 0;
}

This is an assignment on nested loops, so we're supposed to use 4 for loops. I suspect that there's going to be 2 pairs of nested for loops. Can anyone help me out?

Greetings.
Sorry, I didn't have time to really sit down and think.
Can't get 4 for loops, but I've got a while nested with 3 for loops.
Take it as a reference if you like.
I'll spend some more time to come out with one with 4-For loops. :cheesy:

I agree, thanks for replying. I can't belive you went out of your way to write that code. I'm not sure if I understanding all the logics of it so I'll continue to study it and pursue the 4 for loops method. I've gotten a bit further already.

hi mrlucky0, heres a similar prog.chk this also out.i feel this is quite simple than that of red_evolves.

#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int n,k,no,i,j,a,b,c;
cout<<"\nenter n:";
cin>>n;
if(n%2==0)
n++;
for(i=1;i<=n;i+=2)
{
for(j=i;j<n;j+=2)
cout<<" ";
for(k=1;k<=i;k++)
cout<<"*";
cout<<"\n";
}
for(i=n-2;i>=1;i-=2)
{
for(j=i;j<n;j+=2)
cout<<" ";
for(k=1;k<=i;k++)
cout<<"*";
cout<<"\n";
}
getch();
}

Yes, I was attempting to write a program similar to that. Looks like you found it. Eventually I was able to figure it out. Here's my rendition, which is not too different. But I swear, I did it on my own!
