27. Multiple Namespaces

Your task is to declare two namespaces:

• namespace UART with variable int baudRate = 115200;
• namespace SPI with variable int clockSpeed = 1000000;
   

Example

Output:

UART Baud: 115200
SPI Clock: 1000000

Why this output?

Because variables from each namespace are accessed explicitly: UART::baudRate and SPI::clockSpeed.

Question Significance

This shows how multiple namespaces keep values organized and prevent naming collisions.
