c++ hw In this hw, you're going to be working with partially filled arrays that are parallel with each other. That means that the row index in multiple arrays identifies different pieces of data for the same person. This is a simple payroll system that just calculates gross pay given a set of employees, hours worked for the week and hourly rate. code format: // TODO: Add function prototypes for all the declared functions // TODO: Declare two functions to compute the highestPay and lowestPay// HINT: Each should return the index of the correct value in the grossPay array. /* TODO: Create a function calledgetEmployeeNames Arguments : Name array(first and last name) Maximum size Return the number of names filled.*/ /* TODO: Create a function calledgetHourlyPay Arguments : NameArray(filled in Step 1) HourlyPayArray(starts empty) NumberOfNamesFilled(from Step1)*/ int main(){ // TODO: Declare an array of strings for the employeeNames able to hold a…

C++ Coding: ArraysTrue and False Code function definitions for eoNum() and output(): Both eoNum() and output() are recursive functions. output() stores the even/odd value in an array. Store 0 if the element in the data array is even and store 1 if the element in the data array is odd. eoNum() displays all the values in an array to the console.
vowelIndex Write a function vowelIndex that accepts a word (a str) as an argument and returns the index of the first vowel in the word. If there is no vowel, -1 is returned. For this problem, both upper and lower case vowels count, and 'y' is not considered to be a vowel. Sample usage: >>> vowelIndex('hello') 1 >>> vowelIndex('string') 3 >>> vowelIndex('string') 3 >>> vowelIndex('BUY') 1 >>> vowelIndex('APPLE') 0 >>> vowelIndex('nymphly') -1 >>> vowelIndex('string')==3 True >>> vowel Index ('nymphly')==-1 True

C code blocks Implement a function which receives a character array and determines if the word is a palindrome or not. A palindrome is a string that is spelt the same way forwards and backwards (see the example below). The function should return 1 if the character array is a palindrome and 0 if it is not. Write the entire function in the space below. Your answer should not include the function prototype, the main function or any include statements. The function should not contain any printf statements. Define your function in the same way as the given function prototype. Function prototype: int palindrome(char a[]); For example: Input Result hello 0 radar 1 acca 1

Help and show me how to fix an error? def kwargs_to_args_decorator(*args, **kwargs): This question is meant to test your knowledge of creating a decorator that accepts an arbitrary number of positional and keyword arguments, to decorate a function that accepts an arbitrary number of positional and keyword arguments, and alters the arguments before passing them to the decorated function. When the decorated function is invoked, this decorator should modify the arguments the decorated function receives. This decorator should filter out all positional arguments passed to the decorated function, which are found in the positional arguments passed to the decorator when the decorator was initialized. It should also filter out all keyword arguments with keys that are found in the keyword arguments given to the decorator when the decorator was initialized. After performing the modifications to the arguments, the decorator should invoke the decorated function with the modified arguments and…
