Please provide C++ program for above question.​

Use the knowledge in computational language in C++ to write the a code with alphabetical order of author name.

An Array is a set of values ​​arranged in lists and accessible through a positive numeric index. So, we have that each position of our Array is a variable of the type of our Array, so we have to have a way to initialize this set of variables.

12.2 E-Z LOAN
A loan obtained from a lending institution is typically paid off over time using equal monthly payments over a term of many months. For each payment, a portion goes toward interest and the remaining amount is deducted from the balance. This process is repeated until the balance is zero. Interest is calculated by multiplying the current balance by the monthly interest rate, which is usually expressed in terms of an Annual Percentage Rate (APR). This process produces an Amortization Schedule where the amount applied to interest is gradually reduced each month and the amount applied to the balance grows. For example, the following amortization schedule is for a loan of $ 10.000 at an APR of 3.9% over a term of 30 months:3 will match months 12, 24, and 30 respectively.

i need the full code for 6.1.3 code hs circles and squares please answer please help

Write a function named count_vowels that accepts two arguments: a string and an empty dictionary. The function should count the number of times each vowel (the letters a, e, i, o, and u) appears in the string, and use the dictionary to store those counts. When the function ends, the dictionary should have exactly 5 elements. In each element, the key will be a vowel (lowercase) and the value will be the number of times the vowel appears in the string. For example, if the string argument is 'Now is the time', the function will store the following elements in the dictionary: 'a': 0 • 'e': 2 'i': 2 'o': 1 'u': 0 The function should not return a value.

9.11: Array Expander
Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is twice the size of the argument array. The function should copy the contents of the argument array to the new array, and initialize the unused elements of the second array with 0. The function should return a pointer to the new array. Demonstrate the function by using it in a main program that reads an integer N (that is not more than 50) from standard input and then reads N integers from a file named data into an array. The program then passes the array to your array expander function, and prints the values of the new expanded array on standard output, one value per line. You may assume that the file data has at least N values.

Prompts And Output Labels. There are no prompts for the integer and no labels for the reversed array that is printed out.

Input Validation. If the integer read in from standard input exceeds 50 or is less than 0 the program terminates silently.

Write a program that uses while loops to perform the following steps:
a. Prompt the user to input two positive integers. Variables: firstNum and secondNum
(firstNum must be less than secondNum) (use while loop); create a user-defined function
called validateUserInput() to validate the user's input. Use Call-by-Value.
validateUserInput() is a value returning function.

b. Output all odd numbers between firstNum and secondNum. (use while loop); create a
user-defined function called oddNumbers(). Use Call-by-Value. oddNumbers() is a void
function.

c. Output the sum of all even numbers between firstNum and secondNum. (use while
loop); create a user-defined function called sumEvenNumbers(). Use Call-by-Value.
Declare a variable called sumEven in the main() for the sumEvenNumbers().
sumEvenNumbers() is a valuereturning function. Use sumEven to hold a returned value.

d. Output the numbers and their squares between 1 and 10. (use while loop): create a
user-defined function called displaySquareNumbers(). Call-by-Value.
displaySquareNumbers() is a void function.

e. Output the sum of the square of the odd numbers between firstNum and secondNum.
(use while loop); create a user-defined function called sumSqureOddNumbers(). Use
Call-by-Value. Declare a variable called sumSquareOdd in the main(), for the

sumSqureOddNumbers(). sumSqureOddNumbers() is a value returning function. Use
sumSquareOdd to hold a returned value.

f. Output all uppercase letters. (use while loop); create a user-defined function called
displayUppercaseLetters(). Use Call-by-Value. displayUppercaseLetters() is a void
function.
