Code for Exercise 1, Problem 3 Send message to serial monitor depending on which button has been actuated

Component list is as follows:
Pushbutton circuits that generate a logic high are connected to digital pins:
2 - Button A
12 - Button B
8 - Button C
7 - Button D

LEDS cicuits are on the following digital pins:
5 - Orange LED
6 - Blue LED
10 - Green LED
9 - Red LED

Servo control line is on digital pin 11

//designate the LED pins as OUTPUTS

pinMode(10,OUTPUT); //Green LED

//designate pushbutton pins as INPUTS
pinMode(2,INPUT); //Button A
pinMode(7,INPUT); //Button D
pinMode(8,INPUT); //Button C
pinMode(12,INPUT); //Button B

//attach pin 11 as the servo control line
