christmas Tree patterns in C++

The program of create Christmas Tree in C++ we only used for loop and if- statement.

The program can be easily understood, so the variable name in the program is given according to their task.

Here in this page we will create Christmas Tree in C++ Here heart size will be depend on user input meaning that dynamic heart will be print on screen.

Here is the program,

#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
   int num,count=0;
    int center=30; // print tree into center of screen
     cout<<"Enter Number(Minimum 4 and Max 7): "; cin>>num;
   
   cout<<"/n/n"; count=num-2;int joint=0; while(count>0) // count pyramid of tree
    {
      for(int row=0;row<num-count+1;row++) { for(int blank=num-joint+center;blank>=row; blank--)
         {
           cout<<" "; // print whole left side space
         }
      for(int left =0;left<=row+joint;left++)
         {
           cout<<"*"; // print left side part of tree
         }
      for(int right =0;right<=row+joint;right++)
        {
           cout<<"*";  // print right side part of tree
        }
     cout<<endl;
   }
 count--; // decrement in number of pyramid
 joint++; // increase size of pyramid by one row
}

 //print bottom of tree
int v;
 for(int stem = 0;stem<2;stem++)
  {
    if(num==4)
        v=1;
    else
        v=0;
    cout<<setw(v+center+num+num-num/2);
    cout<<"| |"<<endl;
  }
 return 0;
}

OUTPUT

Enter Number(Minimum 4 and Max 7): 5
                        **
                       ****
                      ******
                       ****
                      ******
                     ********
                    **********
                      ******
                     ********
                    **********
                   ************
                  **************
                       | |
                       | |
