Need a completed C++ program for each of the following pseudocodes: 2a. //initialize array arr[20] index = 0 for 1 to 20 //get user input value into array arr[index] = input index = index + 1 //calculate average avg = sum(arr) / 20 i = 0 // iterate for 20 numbers for 1 to 20 //print each number's difference print avg - arr[i] i = i+1   2b. //initialize array arr[20] index = 0 // loop for 20 integers for 1 to 20 //get user input value into array arr[index] = input index = index + 1 // if user enters -1 exit from loop if input is -1 break //calculate average avg = sum(arr) / arr.length i = 0 // iterate for array length for 1 to arr.length //print each number's difference print avg - arr[i] i = i+1
