Chapter 2, Problem 14PP

Write a program that calculates the total grade for N classroom exercises as a percentage. The user should input the value for N followed by each of the N scores and totals. Calculate the overall percentage (sum of the total points earned divided by the total points possible) and output it as a percentage. Sample input and output is shown below.

How many exercises to input? 3

Score received for exercise 1: 10

Total points possible for exercise 1: 10

Score received for exercise 2: 7

Total points possible for exercise 2: 12

Score received for exercise 3: 5

Total points possible for exercise 3: 8

Your total is 22 out of 30, or 73.33%.

Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
Question 1 Write a program that asks the user to enter the number of passengers in an airplane and the weight of baggage for these passengers. Your program should then print the average weight of all baggage; it should also print the weights in reverse order. Sample run: Enter the number of passengers in the airplane: 8 Enter the weights of 8 baggage: 16 45 60 13 24 29 50 30 The average weight of all baggage is 33.375 The entered weights in reverse order are 30 50 29 24 13 60 45 16
Statistics are often calculated with varying amounts of input data. Write a program that prompts for and takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics. Example program run (the user types only the numbers, in this case 15 20 0 5 -1): Enter numbers separated by spaces, with a negative number to quit: 15 20 0 5 -1 Average = 10 Max = 20 #include <iostream>using namespace std;/* program that prompts for and takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics.  Example program run (the user types only the numbers, in this case 15 20 0 5 -1):  Enter numbers separated by spaces, with a negative number to quit:15 20 0 5 -1 Average = 10 Max = 20*/ int main() {    /* Type your code here. */    return 0;}
