What is the c++ code for these questions (pseudo code provided)

1. Design the logic for a program that allows a user to enter 20 numbers, then displays each number and its difference from the numeric average of the numbers entered.

2. Modify the program so that the user can enter any amount of numbers up to 20 until a sentinel value is entered.

// Start

// Declarations

// num SIZE = 12

// num numbers[SIZE]

// num value = 0

// num counter = 0

// num total = 0

// num average = 0

// num diffFromAvg = 0

// num SENTINEL = -1

//

// output "Please enter a positive number: "

// input value

// while ((counter < SIZE) AND (value <> SENTINEL) )

// total = total + value

// numbers[counter] = value

// counter = counter + 1

// if (counter <> SIZE)

// output "Please enter a positive number: "

// input value

// endif

// endwhile

//

// if (counter > 0) then

// average = total/counter

// for i = 0 to counter - 1

// diffFromAvg = numbers[i] - average

// output "Number[",i,"]: ",numbers[i]," Difference from Average is ",diffFromAvg

// endfor

// else

// output "Processing incomplete. No values in the array."

// endif

// Stop
