When we consider the implementation of our code, we need to comprehend the concepts of what makes a effective algorithms from a horrible algorithms. Having a bad code can undermines some fundamental flaws in our thinking of implementation our algorithms and presentation. Good code is well-organized and written thought out. One of the key factors of a good code is data and operations in classes fit together effectively. Consider the bad code from being too complicated from your user to actually understand or acknowledge or what are you writing or explaining about.

Take this for example:

#include <iostream>
using namespace std;

int main()
{
  char mlevel;              // this is a valid char                   
  bool chalmers;
  string name;
  double r, g, c, peoplewhoareadults;                                            
                cout << "Hi" << endl;
				cin >> name >> endl;
		cin >> r >> endl;                                            
		cin >> g >> endl;
		cin >> c >> endl;
		cin >> peoplewhoareadults >> endl;
		cin >> chalmers >> endl;
  cout << "What is your motivation?\n"
       << " a. Amazingly Motivated\n"
	   << " b. Basicly a good worker\n"
	   << " c. Can't get good help no more\n"
	   << " d. Don't plan on work from me\n"
	   << " e. Elevated Slothfullness \n\n"
	   << "Enter the letter of your choice: ";
	   cin >> mlevel;

	   if(mlevel=='a')   // this is an if statement
	   {
	   if(r>=0.5)
	   {
	   if(g<=5)    // checks if g <= 5
	   {
	   cout << "burn books" << endl;
	   }
	   else
	   {
	   cout << "clean the bathroom" << endl;
	   }
	   }
	   else
	   {
	   if(g<=5)
	   {
	   cout << "Go get more g" << endl;
	   }
	   else if(g>=5 && g<10)
	   {
	   cout << "Mow grass" << endl;
	   }
	   else
	   cout << "Do laps in the tractor" << endl;
	   }
	   // This is a comment right in the middle that says I stayed up too late and didn't do my homework
	   // and now my code looks horrible. Large paragraphs of comments makes your code harder to read
	   // try using short statements to briefly explain what a block of code is actually doing instead
	   // of paragraphs that state nothing really important.
	   }
	   else if(mlevel=='b')
	   {
	            if(chalmers==1||peoplewhoareadults>c)
		{
		    cout << "Scrub floors on hands and knees" << endl;
			}
			   else
			   {
			   cout << "Mop the floor." << endl;
			                    }
						}
		else if(mlevel=='c')
		{
		if(r<=1.5)
		{
		                         cout << "Lean on rake." << endl;
								 }
					else
					     cout << "Lean on broom inside" << end;
		}
		else if(mlevel=='e')
		{
		  cout << "Stay in bed" << endl;
		}

		return 0;
	}

This code suffers from lack of indentation, oblivious code comments, unnecessary usage of variables, and a bunch of CIN statements which makes the whole algorithm very hard to read. In order to prevent this common errors that most beginner programmers have been habited to use, we can start off with writing comments first with clear objective and information for any viewers to read clearly.
