Program to print the Cot Bed Pattern

  • Last Updated : 20 May, 2021

The given task is to draw the Cot Bed pattern using ‘$’

Cot Bed Pattern:  

$$$$$$$$$$$$$$$$$$$$$$$$$
 $     $ $     $ $     $
  $   $   $   $   $   $
   $ $     $ $     $ $
    $       $       $
   $ $     $ $     $ $
  $   $   $   $   $   $
 $     $ $     $ $     $
$$$$$$$$$$$$$$$$$$$$$$$$$

Below is the code to implement the above problem:

Program:  

C++




// C++ program to print
// the Cot Bed Pattern
 
// header files
#include <bits/stdc++.h>
using namespace std;
 
// function to print the pattern
void pattern(int nos, int i, int space)
{
    char prt = '$';
    int s, j;
 
    // loop for the spacing between the $ sign
    for (s = nos; s >= 1; s--)
    {
        cout <<" ";
    }
 
    // skipping the $
    for (j = 1; j <= i; j++)
    {
        if (space != 0)
        {
            if (i == 9 && j == 1)
            {
                continue;
            }
        }
 
        // printing the $
        if (i == 1 || i == 9)
        {
            cout << prt;
        }
        else if (j == 1 || j == i)
        {
            cout << prt;
        }
        else
        {

        }
    }
}
 
// Driver code
int main()
{
    int i, nos = 0, nosp = -1, nbsp = -1;
    for (i = 9; i >= 1; (i = i - 2))
    {
 
        // printing the first upper triangle
        pattern(nos, i, 0);
 
        // printing the second upper triangle
        pattern(nosp, i, 1);
 
        // printing the third upper triangle
        pattern(nbsp, i, 1);
 
        cout << endl;
        nos++;
        nosp = nosp + 2;
        nbsp = nbsp + 2;
    }
 
    nos = 3, nosp = 5, nbsp = 5;
 
    for (i = 3; i <= 9; (i = i + 2))
    {
 
        // printing the first lower triangle
        pattern(nos, i, 0);
 
        // printing the second lower triangle
        pattern(nosp, i, 1);
 
        // printing the third lower triangle
