Nested if statements are simply if statements placed inside other if statements. While they provide a way to handle complex decision-making in your code, they can become difficult to read and maintain, potentially leading to logical errors that could be exploited. This doesn't inherently make them a direct 'security risk' in the way a SQL injection is, but the increased complexity can create opportunities for bugs, which, if exploitable, could lead to security vulnerabilities. Using best practices can significantly reduce these risks.

| Term | Definition |
|---|---|
| 1. Code Smell | A. A potential bug caused by confusing different conditions |
| 2. Cyclomatic Complexity | B. A coding practice to make code more understandable |
| 3. Readability | C. A measure of the number of independent paths through the code |
| 4. Logic Error | D. A characteristic in code that suggests there is a deeper problem |
| 5. Refactoring | E. Restructuring existing computer code—changing the factoring—without changing its external behavior |
