How to Draw an Arrow with Asterisk in C++

This is the cool and logic building C++ program for beginners. The purpose of this C++ code is to understand the different programming terms in different ways. The program will generate an arrow at the end of executing.

Source Code

#include <iostream>
#include <unistd.h>
using namespace std;
void welcomeScrean(void);
void sleep();
void draw();
int main()
{
 system ("color F0");
 
 welcomeScrean();
 draw();
 return 0;
 
}

void welcomeScrean(void){
  cout<<"\a"
  <<"\t*******************************************************"<<endl
  <<"\t*******************************************************"<<endl
  <<"\t**                   Welcome To                      **"<<endl
  <<"\t**                    Draw By *                      **"<<endl
  <<"\t**                    Program                        **"<<endl
  <<"\t*******************************************************"<<endl
  <<"\t*******************************************************"<<endl
  <<endl
  <<endl;
  sleep();

}
void sleep(){
 sleep(1);
 for (int i=0 ; i<3;i++)
 {
  if (i==0)
  {
   cout<<"\tJust a min ";
  }//END IF i
  cout<<"\a.";
  sleep(2);
 }//
}
void draw(){
 int size,i,j,k,k1,p;
 cout<<"\n\n\tEnter A No : ";
 cin>>size;
 cout<<"\n\n\t";
 for (i=0;i<size;i++)
 { 
  k = size-i;
  for (j=0;j<k;j++)
  {
   cout<<" ";
  }
  for (j=k;j<size;j++)
  {
   cout<<"*";
  }
  cout<<"I";
  
  for (j=k;j<size;j++)
  {
   cout<<"*";
  }
  cout<<"\n\t";
 }
 k = size / 2;
 k1 = k / 2;
 p = size-k1;
 for (i=0;i<k;i++)
 {
  for(j=0;j<p;j++)
  {
   cout<<" ";
  }
  for(j=0;j<k1;j++)
  {
   cout<<"*";
  }
  cout<<"I";
  for(j=0;j<k1;j++)
  {
   cout<<"*";
  }
  cout<<"\n\t";
 }
}
