- C++ CODE ONLY: Write a program that takes as input five numbers and outputs the mean (average) and standard deviation of the numbers. If the numbers are X₁, X2, X3, X4, and x5, then the mean is X = (X1 + X2 + X3 + x4 + x5 ) / 5 and the standard deviation is: (x₁−x)²+ (x₂-x)²+ (x¸¯x)²+(x¸−x)²+(x¸¯x)² S = 5 Your program must contain at least the following functions: 1. a function that calculates and returns the mean; and, 2. a function that calculates the print standard deviation. Input 1.5 integers Output Enter five numbers: 2 3 9 10 11 The mean is 7.00. The standard deviation is 3.742. Enter five numbers: 7 7 8 9 11 The mean is 8.40. The standard deviation is 1.497.arrow_forwardin C program For this assignment, you will need to build a program that does the following: The process of finding the largest value is used frequently in computer applications. For example, a program that determines the winner of a sales competition would input the number of units sold by each salesperson. The salesperson who sells the most units wins the contest. Write a program that has the user input a series of 10 integers and determine and print the largest integer. Your program should use at least the following three variables: counter: A counter to count to 10 (i.e., to keep track of how many numbers have been input and to determine when all 10 numbers have been processed). number: The integer most recently input by the user. largest: The largest number found so far. You must use a while loop as well as an if statement. Properly give the user instructions, take input and print the largest number before saying goodbye to the user. The program output will look something like…arrow_forwardC Programming Write a program that reads an integer from the user (keyboard), namely n. Yourprogram should print all positive numbers that are smaller than n and whosedigits sum up to a perfect square number.(An integer is a perfect square if it hasan integer square-root for example 25) You should print the numbers in ascendingorder and print their digits separated by “:“ symbol from the least significant digitto the most significant digit on the same line as the number. At the end of eachline you should also print the sum of the digits of the number. Example:If the user enters n : 30, then the output should be as follows:1 1 14 4 49 9 910 0:1 113 3:1 418 8:1 922 2:2 427 7:2 9arrow_forward
- Based on the following C code: { int x, y, z, sum, total; int *pt1, *pt2, *ptc; x = 99; y = 86; pt1 = &y; pt2 = pt1; ptc = &x; z = (*(&y))/2 + (*pt2)/3 + 5; sum = (x + y + *pt1 + *pt2 + z)/3; total = sum + *ptc + *pt1; } (1) What is the value of z? (2) What is the value of sum? (3) What is the value of the total? (4) What is the address of the data 86?arrow_forwardPlease modify the C++ data structure program below to detect and display multiple candidates with the same number of votes: multiple winners, multiple candidates with the second highest number of votes, multiple candidates with the third highest number of votes, and so on. Suppose the candidates are A, B, C, D, E, F and G and their votes are: A 100 B 200 C 200 D 400 E 100 F 400 G 300 H 300 Then your program should display, A Fourth Place B Third Place C Third Place D First Place E Fourth Place F First Place G Second Place H Second Place with the amount of votes they received, for example: A Fourth Place with 100 votes, B Third Place with 200 votes, C Third Place with 200 and etc. Text file names and program below. Thank you. votes.txt Johnson Miller Robinson Duffy Asthon Sampson Adams Williams ________________________________________________________________________________ #include <array> #include <cassert> #include <cmath> #include…arrow_forwardC++ Write a program that takes as input an arithmetic expression followed by a semicolon ;. The program outputs whether the expression contains matching grouping symbols. For example, the arithmetic expressions {25 + (3 – 6) * 8} and 7 + 8 * 2 contains matching grouping symbols. However, the expression 5 + {(13 + 7) / 8 - 2 * 9 does not contain matching grouping symbols. If the expression contains matching grouping symbols, the program output should contain the following text: Expression has matching grouping symbol If the expression does not contain matching grouping symbols, the program output should contain the following text: Expression does not have matching grouping symbols.arrow_forward
- By using c++programming, plz complete the codingarrow_forwardIn c++ you have 5 different countries, Each country contains two different integers. Example England(30, 10) in that format, how will you calculate and find the country with the smallest integers between those 5 countries and also calculate and display the total steps that country has compared to the other countries. Example…England has 50 steps.arrow_forward
