Always leave the campground cleaner than you found it. If you find a mess on the ground, you clean it up regardless of who might have made it.

TL;DR: Follow Uncle Bob's boy scout rule.

Problems

• Readability

• Maintainability

Solutions

1. Leave the code better

2. Change it

Context

We read code many more times than we write.

We must take ownership of code with errors and leave it better.

Sample Code

Wrong

    int mult(int a,int  other)     { int prod      prod= 0;       for(int i=0;i<other  ;i++)         prod+= a ;          return prod;     } // Formatting, naming, assignment and standards inconsistent

Right

int multiply(int firstMultiplier, int secondMultiplier) {  int product = 0;   for(int currentIndex=0; currentIndex<secondMultiplier; currentIndex++) {    product += firstMultiplier;   }  return product; } // or just multiply them :)

Detection

[X] Semi-Automatic

We can use other code smell detectors and leave the code in a better shape.

Tags

• Standards

Conclusion

We must follow the Boy Scout rule and leave the code better.

One broken window, left unrepaired, instills in the inhabitants of the building a sense of abandonment. People start littering. Graffiti appears. Serious structural damage begins. In a relatively short span of time, the building becomes damaged
