Question

Hello I need help fixing some things so that the C++ code follows all the requirements listed below. Thanks,

This needed to fix:

Rule 3 (Not Satisfied):

In rule 3 it is asked to use conditional statements only for the base-case and for all other conditional expressions you must use ternary operators. You have used "if", "else" statements multiple times so this rule was not satisfied.

Rule 6 (Not Satisfied):

As per this rule you are permitted to use upto 4 "cout" statements but you've used 6.

Rule 7 (Not Satisfied):

As per this rule, boundary straight line should be right on edge points or one beyond beyond edge but your boundary straight line is two points beyond the edge line.

Requirements:

Here are the required two function declarations for your recursion work: int main() { pattern( 0, 16 ); void pattern int left, int length ) Your submitted pattern() function, the recursive function must abide the following rules (which is our rubric for this assignment): 1. Use the same pattern function header: void pattern(int left, int length) 2. Function pattern remain as a recursive function, no iterative approach. 3. Only one (1) branch statement is allowed - the base case. All other conditional expression must use the ternary statement. You may cascade as many conditional expression, so long it it inside of a single statement; 4. Inside the pattern() you make make two, exactly two calls to itself, pattern(); // like the recursive methods for a binary tree! 5. Making (2) two loop each contain a single statement 6. Total of upto four (4) cout statements 7. The boundary straight line can be right on the edge points or one beyond the edge.

Code:

#include<iostream>
#include<iomanip>

using namespace std;

void pattern(int left, int length)
{
if (length == 0) return;

pattern(left, length / 2);

(left*2 ) ? cout << "* " : cout << "" /*do nothing*/ ; //ternary statement

    for (int i = 0; i < left * 2 - 1; i++)
   cout << " ";
  

for (int i = 0; i < length; i++)
cout << "* ";
for (int i = 0; i < left * 2; i++)
cout << " ";

//( left*2 ) ? cout<<"*"<<endl : cout<<" *"<<endl ; //ternary statement instead of if else

cout<<"*"<<endl;

pattern(left + length / 2, length / 2);
}

int main()
{
pattern(0, 16);
}

Desired Output:

My Output:

Answer 1

//Solution:

#include<iostream>
#include<iomanip>

using namespace std;

void pattern(int left, int length)
{
if (length == 0) return;

pattern(left, length / 2);

(left*2 ) ? cout << " " : cout << "" /*do nothing*/ ; //ternary statement

for (int i = 0; i < left * 2 - 1; i++)
cout << " ";
  
for (int i = 0; i < length; i++)
cout << "* ";

for (int i = 0; i < left * 2; i++)
cout << " ";

cout<<" "<<endl;

pattern(left + length / 2, length / 2);
}

//Main Function
int main()
{
//Call pattern and pass two integer parameters
pattern(0, 16);
}
