70. ADCChannel Constructor Validation

Create a class ADCChannel that represents an analog-to-digital converter (ADC) configuration on a microcontroller. The object must validate inputs inside the constructor, ensuring the channel and resolution are always safe and legal.

Details you must implement:

• Private members:
  • int channel
  • int resolution
• Constructor Requirements:
  • Create a constructor:

    • ADCChannel(int ch, int res)

  • It must enforce the following rules:
    • Valid channels are 0 to 15
      • If ch < 0, set channel = 0
      • If ch > 15, set channel = 15
    • Valid resolutions are 8, 10, or 12 bits
      • If any other value is provided, set resolution = 12 (safe default)
• Public methods:
  • void print()
    • Should display exactly:

      • CH=<channel> RES=<resolution>

Program behavior (main()):

• Read ch and res
• Construct an ADCChannel object
• Print its internal values

Example 1

Input:

3 10

Output:

CH=3 RES=10 

Example 2

Input (invalid channel and invalid resolution):

20 9

Example Output:

CH=15 RES=12 

Explanation:

• 20 → clamped to 15
• 9 → not in {8,10,12} → default = 12

Constraints:

• You must validate channel and resolution inside the constructor.
• Resolution must fall back to 12 when invalid.
• Output must match exactly.
