Format Reaction Line

Task

Implement the function format_reaction_line.

• Write a function that formats a single reaction according to the PA specification
• The format is: (username) reaction with some leading spaces
• Write the result into a provided buffer

Function Signature

struct Reaction {
	char user[16];
	char message[16];
};
 
// Format a reaction as "                        (username) reaction"
// buffer should have enough space for the formatted string
void format_reaction_line(struct Reaction* reaction, char* buffer);

Notes

• Use sprintf() or snprintf() to format the string
• The format includes leading spaces (about 24 spaces to align with chat lines)
• Then (username) with no spaces inside the parentheses
• Then a space, then the reaction message
• According to the PA spec: “some space before the (, no space between the () and the username, and some space after the ) before the reaction message”
• You can use a format like: " (%s) %s" (24 leading spaces)
• Include <stdio.h> for sprintf()

Example

Reaction	Output
user=“joe”, message=”👍“	(joe) 👍
user=“aaron”, message=“cool”	(aaron) cool
user=“alice”, message=”😬“	(alice) 😬
