C++ coding 1. Formatted TimeWrite a C++ program that asks the user to input a positive integer representing the elapsed numberof seconds. Your program should then output the elapsed hours, minutes, and seconds in thefollowing format:hours : minutes : secondsSample Input/Output:Please enter the number of elapsed seconds: 72502:0:50Submit your solution in formatted_time.cpp.2. Monte Carlo Area CalculationsYou are not required to solve nor submit this problem, just read it and understand its solution (I amattaching its solution with this assignment) Understanding it will make it easier for you to solve problem3 below.Refer to the figure below, and write a C++ program which prompts the user to enter the values ofthe rectangle width (W), its length (L), and the circle radius (r). You can assume that W S L andrsW/2 (the user is expected to provide input that satisfies these conditions; i.e. you are notrequired to check or handle the case when the input is invalid). You are asked to calculate the bluearea in the figure below using two methods:(a) Method 1- Simply calculate the area using the equation (Use n = 3.1416):Blue area = Rectangle Area - Circle Area = L x W – ar².(b) Method 2 - Use the Monte Carlo method (See detailed explanation on the next page).OriginComplete the solutions and provide two cout statements which print the results after using eachof the two methods, so that you can compare them.About the Monte-Carlo MethodThe Monte Carlo method relies on repeated random sampling to obtain numerical results, and it iswell-known and used in different engineering and other applications. We will use Monte Carlo inthis problem to obtain an approximate value of the blue area. The idea is to generate a large numberof random points within the rectangle area, and then count the number of points that fall within theblue area (i.e. outside the circle). The blue area can then be estimated to be equal to area of therectangle multiplied by the percentage of points that fell outside the circle. For example, if 70% ofthe generated random points fall outside the circle and 30% fall inside it, then the blue area isapproximately equal to 0.7xrectangle area. The larger the number of points, the more accurate theapproximation will beHow to implement it in C++As you know from the carlier assignments, in order to generate random values in C+, you willneed to include the stdlib.h and time.h libraries (#include and #include). Youalso need to add the srand(time(0)); statement at the beginning of main (include the srandstatement only once; do not repeat it for every random value). You can then use the rand( )function and the RAND_MAX constant to generate a random point (x, y) within the area of therectangle. That is, you need to generate random x and y coordinates such that:s xsand -< yswhere we have assumed that the circle and rectangle are co-centered at the origin for simplicity.In order to check if the point is outside the circle, we simply need to check if (x? + y? > r?).You will need to generate a large number of random points (e.g. 1000 or 10000 points) to get agood estimate of the area.

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

in C++ Review - for loops, if-else, switch, functions Many computer applications, such as Microsoft Excel, can compare date values that occur after January 1, 1900. For example, these programs can determine if 06/06/99 is less than (comes before) 11/01/00. They use January 1, 1900 as their reference point. This becomes day 1. All other dates are calculated as to the number of days they are relative to January 1, 1900. For example January 2, 1900 is equal to 2. October 31, 2000 is equal to 36829. Notwithstanding, Excel cannot tell you which day of the week these two dates fell on. For this assignment, you are to write a C++ program which will: Have the User enter in a date. Calculate the "day value" of that date. For this you will need to write several functions as stated below. A function that determines if a year is a leap year. A function that determines the number of days in a month. Remember if the year is a leap year then February has 29 days. You…

using loops in C++ Write a program that will predict the size of a population of organisms. The program should ask the user for the starting number of organisms, their average daily population increase (as a percentage, expressed as a fraction in decimal form: for example 0.052 would mean a 5.2% increase each day), and the number of days they will multiply. A loop should display the size of the population for each day.Prompts, Output Labels and Messages .The three input data should be prompted for with the following prompts: "Enter the starting number of organisms: ", "Enter the average daily population increase (as a percentage): , and "Enter the number of days they will multiply: " respectively. The population sizes displayed should appear on separate lines, each of the form "On day D the population size was P." where D is the day number (starting with 1) and P is the population you calculated for that day.Input Validation.Do not accept a number less than 2 for the starting size of…
Programing in c This program will calculate how pricy two products will be in 2030. It will begin by asking the user for the current price of the products. Then, it will print these values out, so the user knows the values were saved correctly. Next, it will ask the user for the inflation rate. After this, the program should multiply the current prices by the inflation rate. When done, it should print out the estimated-inflated values. For this task, you will need to define a structure with two members. These two members will be the products whose inflated price will be calculated. In the example I chose salt and soap. You will also need a local variable in main that holds the value of the inflated rate. Lastly, this process should be ran twice, each time for a different country. Therefore, you will need to declare two variables of the same structure type. One declaration for country1 and one for country2. The example is running estimated values for Mexico and Canada. You may implement…
