Write an algorithm that computes the Body Mass Index (BMI) given the heights and weights of students. The algorithm should first read the total number of students and then read the height and weight of each student to calculate and print the BMI category A student is considered Underweight if the BMI is less than or equal to 18.5; Normal Weight if between 18.5 and 24.9; Overweight if between 25 and 29.9; and Obese if greater than or equal to 30.

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…

Design an algorithm for a problem that processes results of a swimming competition. The program will set a number of competitors, obtain their names from the user, and uses random number generator to get the results (in seconds, as real numbers with three digits after the decimal point). Then it will find and display the average timefor all competitors, andthe names and best three results (first, second, and third places). 1. Set a number of competitors as a constant TOTAL (no more than 10)   2. Declare two arrays to hold names and results (an actual array should have different name than the formal array in the function definitions)   3. Call functions to fill the arrays with names (user entries) and results (random decimal numbers)   4. Print all names and results as a table with appropriate titles   5. Display the average time (by calling function getAverage())   6. Sort the array of results and corresponding names   7. Print names and results for the first three places (first…
