#include <cmath>
#include <iomanip>
using namespace std;
int main()
{
int x, y, tempL, tempR, middle;
cout << "Please enter # of diamonds: ";
cin >> y;
while (y){
cout << "Please enter the size: ";
cin >> x;
     if (x % 2 == 0) { middle = tempL=tempR = x / 2 ; }
          else { middle=tempL= tempR = x / 2 + 1 ; }
                for (int i=1; i<= x; i++){
                     for (int j=1; j<=x; j++){
                     if (j >= tempL && j<=tempR)
                          cout <<" *";
                             else

                        cout << endl;
                       if (i<middle){ tempL--; tempR++; }
                  else {tempL++; tempR--; }
                 }
                 y--;
                 }
                return 0;

Someone posted something almost like what you wanted to do a couple days ago. I can't find the post, but the code was something like this:

#include <iostream>

using namespace std;

void printStars(int len)
{
    if (len == 0)
        return;
    for (int i = 0; i < len; ++i)
        cout << '*';
    cout << endl;
    printStars(len - 1);
    for (int i = 0; i < len; ++i)
        cout << '*';
    cout << endl;
    return;
}

int main()
{
    int size;
    cout << "Please enter the size: ";
    cin >> size;
    printStars(size);
}

I'm sure you can convert it to using loops instead of a recursive function, and modify it to look exactly like what you want.
