This is the logical C++ program in which we make a tree shape. The program represent a tree shape through logic . (this can also be done by hard code like simple cout.).

Source Code

#include <iostream>
#include <unistd.h>
using namespace std;

void welcomeScrean(void);
void sleep();
void draw();
int main()
{

}

void welcomeScrean(void){
