- The problem is from Introduction to Programming and Data Structures with C++, 4th edition (Count positive and negative numbers and compute the average of numbers)Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the average as a floating-point number.If you entire input is 0, display 'No numbers are entered except 0.'Sample Run 1Enter an integer, the input ends if it is 0: 1 2 -1 3 0The number of positives is 3The number of negatives is 1The total is 5The average is 1.25Sample Run 2Enter an integer, the input ends if it is 0: 0No numbers are entered except 0For the program below, assume that a point on a Cartesian plane comprises values representing x and y coordinates. The distance between two points in a Cartesian plane can be calculated using the formula derived from d=√((x2-x1)²+(y2-y1)²). Write a C++ program that prompts a user to input two points on the Cartesian plane and works out the distance between them. Use comments in your code, highlight how you have used the following concepts of C++ : class, object, constructors and destructors.Write a C++ program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered. void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. **DO NOT USE AN ARRAY OR GLOBAL VARIABLES!!!*** YOU MUST USE THE STATED FUNCTIONS. AND INPUT VALIDATION. For FULL CREDIT DISPLAY THE LOWEST SCORE WITH GOOD OUTPUT DESCRIPTION you MUST USE function prototyping.. DO NOT ACCEPT SCORES LESS THAN 0 OR GREATER THAN…
- Write a program in C++ that should calculate the insurnace for a house. use questions below to write your programm. what is your first? what last name? how many people are living in the houes? how much did you bought the house for? how many bedrom does it have? what is the lenght in squre feet? - use Loop so everyone can repeat the programm. use function like "viod" and any other function. and finally use this formula: X/150*y/*50 x is the total price of the house y is the number of bedrooms s is the lenght in square feet.Write a C program that calculates the price of a pizza and prints the receipt as follows: 1- Your program should first ask the user to enter the size of the pizza (integer value 1=large, 2=medium, 3=small) as well as the number of toppings (integer). 2- Your program should then read the pizza basic price (double) as well as the price of a topping ( float ) from the user. 3- Your program should then calculate the total price of the pizza using the following formula: Total price = ( basic price + number of toppings * topping price ) / size; And print a receipt which displays the details of your pizza order as well as the final total price to the screenA particular talent competition has five judges, each of whom awards a score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer’s final score is determined by dropping the highest and lowest score received, then averaging the three remaining scores. Write a C++ program that uses this method to calculate a contestant’s score. It should include the following functions: void getJudgeData(double &, int) should ask the user for a judge’s score, store it in a reference parameter variable, and validate it (do not accept judge scores lower than 0 or higher than 10). This function should be called by the main function once for each of the five judges. void calcScore(double[]) should calculate and display the average of the three scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by the main function and should be passed the five scores. The two functions,…
- In C++, please revise/fix the program below according to the instructions and all the criteria. I believe the problem is in int main(). Thank you. Instruction Write and test a function that returns a copy of its string parameter with no repeated characters. The functions ignore case when they compare letters. The functions return strings whose letters are upper case. Write 2 versions of the function: string remDups(const string& original); void remDups(const string& original, string& nodups); Suppose the original string is “Myrtle has big feet” The function returns MYRTLE HASBIGF Test the functions thoroughly. Criteria compile, run, test the test program compiles, runs, and calls both versions of the function without crashingthe test program tests the functions thoroughly function parameters and returns one function has one constant string reference parameter and returns a stringone function has one constant string reference parameter, one string reference parameter and…programing in c# Write a program that inputs the radius of a circle as an integer and displays the diameter, circumference, and area using the double 3.14159 for PI. You can use Math.PI as well. The following are how these should be calculated: diameter = 2r circumference = 2πr area = πr^2The Taylor’s series for cos(x) is given as:cos(x)=∑(2?)!=1- + - +...∞ (−1)??2??2 ?4 ?6 2! 4! 6!Write a c program to calculate cos(x) should use three recursive functions: float power (float x, float n);float fact (float n);float cosine (float x, float n);
- in 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…a) What is the risk of using strcpy() in C given the code below? void f1(char *str2) { int y; char str1[10]; strcpy(str1, str2);USE C++ programming language 1) State whether the following declarations are valid or invalid. Give reasons for the invalid declarations and draw memory layout for the valid declarations i)int var, *ptr;ptr = &var; ii)float fvar;int *ptr = &fvar;
