39. Button Press Callback

 A button should trigger an action when pressed.
 We already have two callback functions defined:

void onPressA() { cout << "Button A pressed\n"; }
void onPressB() { cout << "Button B pressed\n"; }

Your task is to implement the function:

void simulatePress(void (*callback)())

• It should call the function passed as the callback.
   

In main():

• Input is "A" or "B".
• Based on input, the correct callback function is passed to simulatePress.
   

Example
 Input:

A

Output:

Button A pressed

Input:

B

Output:

Button B pressed
