## 3.13.1: String comparison: Detect word
### Challenge Activity
Write an if-else statement that prints "Goodbye" if userString is "Quit", else prints "Hello". End with newline.
### Code Example
```c
#include <stdio.h>
#include <string.h>
int main(void) {
char userString[50];
scanf("%s", userString);
/* Your solution goes here */
return 0;
}
```
Click the "Run" button to execute your code.
### Explanation
In this activity, you need to add an if-else statement within the provided C code that checks the value of `userString`. If `userString` equals "Quit", the program should print "Goodbye". Otherwise, the program should print "Hello". Both outputs should end with a newline.
- Add the if-else condition after the `scanf` function call.
- Use the `strcmp()` function from `string.h` to compare the strings.
### Expected Behavior
- If the user inputs "Quit", the output should be:
```
Goodbye
```
- For any other input, the output should be:
```
Hello
```

## 3.13.2: Print two strings in alphabetical order
### Challenge Activity
Print the two strings, `firstString` and `secondString`, in alphabetical order. Assume the strings are lowercase. End with a newline.
### Sample Output
If `firstString` is "rabbits" and `secondString` is "capes", the output should be:
```
capes rabbits
```
---
**Important Notes:**
- Make sure to test your solution with various inputs to ensure it works as expected.
- Pay close attention to handling the newline character correctly after the output string.
