Nested If Statements vs. Switch Case: Which to Use?

What are the main differences between nested if statements and switch case?

Nested if statements allow for multiple conditions to be checked in a hierarchical manner, while switch case is used for selecting one of many code blocks to execute based on a variable's value.

When should I use switch case instead of nested if statements?

Use switch case when you have a single variable that can take multiple discrete values, making the code cleaner and easier to read.

Can you give me an example of both?

Sure! For nested if:

   if (x < 20) { 
       // do something 
   } 
}``` 
For switch case: 
```switch (x) { 
   case 10: 
       // do something 
       break; 
   case 20: 
       // do something else 
       break; 
}```
