Need help, C Programming

--- ## 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. For further assistance and detailed explanations, feel free to refer to the [zyBooks catalog](https://learn.zybooks.com). If you encounter any issues or have questions, visit the [Help/FAQ](https://learn.zybooks.com/help/faq) section. --- This instruction set is designed for students enrolled in CIS 161: Introduction to C Programming. It helps in understanding how to compare strings and print them conditionally based on given criteria using C programming language.
