14. UART Initialization Defaults

Simulate initialization of a UART peripheral with optional configuration parameters.

You must create a function that:

• Always takes a baud rate as the first (required) parameter.
• Optionally takes a parity setting (character), with a default of 'N' (no parity).
• Optionally takes a stop bit count (integer), with a default value of 1.

The function must print the final UART configuration in this order:

baud parity stopBits

In main():

• Read two integers: baud and mode.
• If mode == 0
  • Call the function with only baud (use both defaults).
• If mode == 1
  • Read a character parity, call the function with baud and parity (use default stop bits).
• If mode == 2
  • Read a character parity and an integer stopBits, call the function with all three arguments.
• The function should print the configuration directly.
  
   

Example 1

Input:

9600 0

Output:

9600 N 1

Example 2

Input:

115200 1 E

Output:

115200 E 1

Example 3

Input:

38400 2 O 2

Output:

38400 O 2

Constraints:

•  Use default arguments for the optional parameters.
• Do not create multiple overloaded functions for this task.
