1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.
1)Examine the above code that creates the array: a)How is the base type of the array specified? b)How is the length of the array specified? c)How many Strings are actually stored in the array after the array has been created? d)How is the base type of the ArrayList specified? e)How is the capacity of the ArrayList specified? f)What is the capacity of the ArrayList? g)What is the size of the ArrayList?
d) Print all the elements of the array that are greater than the previous element at smaller than the next element. The first and the last element should be excluded. int arr[] = {5,14,66,7,22,39,0,-12,23,91}

AHPA #4: The C ATM Machine• Two people, "a" and "b", have checking and savings accounts.• Create a 2x2 array to hold their amounts: a – checking: $500, savings:$1,000; b – checking: $750, savings: $325.• Have the ATM machine ask the user their name.• Ask the user if they want to withdraw from their checking or their savingsaccount.• Use a switch statement to process different types of accounts.• Create software that will provide an ATM user with theproper change for any dollar amount up to $200.• Example: Run the code for $19, $55, and $200. Is the amount > $100, then provide a $100 bill & subtract $100• Is the amount >= $100, then provide a $100 bill & subtract $100• Is the amount > $20, then provide a $20 bill & subtract $20 [repeat 4times]• Is the amount > $10, then provide a $10 bill and subtract $10• Is the amount > $5, then provide a $5 bill and subtract $5• Provide the remaining amount in single $1 bills so the output should be like shown in…
Section A. Declare and initialize an array myChars containing the following characters: B, C, D, A, M, S and F.Remember to choose the correct data type for the array elements.Section B. Using a WHILE loop, output the elements of the array myChars so that they are displayed on thesame line and separated by a space. Use .length to get the length of the array.Section C. Change the last value of the array myChars to the letter X. Use .length in your code.Section D. Using a FOR loop, output the elements of the myChars array so that they are displayed on the sameline and separated by a dash (an extra dash at the end is okay). Use .length in your code.Section E. Declare an array of int of capacity 10 named thisArray.Section F. Use a FOR loop to populate the array thisArray with the following numbers 5, 10, 15, 20, 25. Thinkof a way to insert these numbers without actually writing “5” or “10” and so on, but by using the variable i ofyour FOR loop. NOTE that this is a partially-filled array and…
