1. Write a C++ program that uses three arrays numbers, squares and cubes each consisting of 7 elements. You have to input values in all the array as per given scenario i.e The numbers array stores the number values from the user. You shall calculate the squares and cubes from number array and store in the square array and cube array. You shall write following functions: a. Program shall also have a function to find count of duplicate numbers in numbers array. You shall pass array of numbers as parameter and shall return count. n b. You are supposed to write function to find and return count of even numbers from array. You shall pass number array as parameter to this function to find count of even from number arrays.

1. Write a program in C where you would perform the following tasks: Write a main() function where you will declare an unsigned integer a. You can assign any value you like. (e.g. a = 5) b. Make a call to function print_multiplication_table(..). You will pass the unsigned integer you defined earlier as an argument to the function call. c. You will define a function called print_multiplication_table..) that takes in an unsigned integer parameter. This function should have void return type and print the multiplication table of the number passed into as an argument. a. For example, if the number passed into the function is 5, you program should print the following: 5 X 1 5 5 X 2 = 10 aE. 5 X 10 = 50
C++ PLEASE MATCH OUTPUT IN PICS (Previous answers were incorrect) In this lab, 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. Parallel Arrays First, you have to define several arrays in your main program employee names for each employee hourly pay rate for each employee total hours worked for each employee gross pay for each employee You can use a global SIZE of 50 to initialize these arrays Second, you will need a two dimension (2-D) array to record the hours worked each day for an employee. The number of rows for the 2-D array should be the same as the arrays above since each row corresponds to an employee. The number of columns represents days of the week (7 last I looked) Functions Needed In this lab,…

Program: final.py Specification First, download the template file, final.py. This file contains the function names and documentation. You are required to add a header comment block with your name, the file name, the current semester, and year. Do not change the function headers, just add your implementation for each function where indicated. Add descriptive comments to your code. Remember to indent all the code for the function. Here are the functions that you will write: • Calculating tips is a common operation and the first function you write for the final project will do exactly that. The function calculate_tip accepts two parameters, the bill amount and the percent to tip, and returns the amount of the tip to write into the bill. The function should return the string "Invalid charge amount" if the charge is not more that 0 and "Invalid tip percent" if the tip is less than 0. Function heading: def calculate tip(charge, tip_percent): Parameter Specification: charge is the total ch…
CODE IN C++ PLEASE......
Please write a detailed code in C++ and also provide some explanations as much as you can, thanks. Write a program to do the following: a) Open a data file that contains velocities. Read the entire file and store the values in an array. b) Call a function and pass the array and its size to the function. c) Calculate the average value of the data. d) if the average value is larger than 2.5 then return it to the main function. Otherwise return a ero to the main function. e) Print the average from the main function. Assume the data file exists and it is located in the same folder as your program.
