userInput(int line);

Gets user input with the option to display the line number (useful for input in loops). It dynamically allocates memory for the input and resizes the buffer if necessary.

• Parameters: int line (line number to display before the input prompt).
• Returns: char* (the user input).

getInput();

Gets a simple one-line user input without displaying the line number. It dynamically allocates memory for the input and resizes the buffer if necessary.

• Returns: char* (the user input).

logMessage(const char* level, const char* message);

Logs a message with a specified log level (e.g., INFO, WARN, ERROR).

• Parameters:
  • const char* level: The log level (e.g., "INFO", "WARN", "ERROR").
  • const char* message: The message to log.
• Returns: void.

logToFile(const char* filename, const char* level, const char* message);

Logs a message to a file with a specified log level.

• Parameters:
  • const char* filename: The log file name.
  • const char* level: The log level.
  • const char* message: The message to log.
• Returns: void.

trimWhitespace(char* str);

Trims leading and trailing whitespace from a string.

• Parameters: char* str: The string to trim.
• Returns: char* (the trimmed string).

toUpperCase(char* str);

Converts all characters in the string to uppercase.

• Parameters: char* str: The string to convert.
• Returns: char* (the converted string).

readFile(const char* filename);

Reads a file's content into a string.

• Parameters: const char* filename: The file to read.
• Returns: char* (the content of the file).

writeFile(const char* filename, const char* content);

Writes a string to a file.

• Parameters:
  • const char* filename: The file to write.
  • const char* content: The content to write to the file.
• Returns: void.

getTimestamp();

Gets the current timestamp as a string in the format YYYY-MM-DD HH:MM:SS.

• Returns: char* (the timestamp string).

maximum(int a, int b);

Finds the maximum of two integers.

• Parameters:
  • int a: The first integer.
  • int b: The second integer.
• Returns: int (the maximum value).

minimum(int a, int b);

Finds the minimum of two integers.

• Parameters:
  • int a: The first integer.
  • int b: The second integer.
• Returns: int (the minimum value).

arrayMax(int* array, size_t size);

Finds the maximum value in an array of integers.

• Parameters:
  • int* array: The array of integers.
  • size_t size: The size of the array.
• Returns: int (the maximum value in the array).
