Using c++ Write a code fragment under your main() that inputs a positive integer n (n<=26) from the user and creates a string containing the first n lower case letters of the alphabet. Use a loop rather than a complex “if” statement. Note that ‘b’ == (char)((int)‘a’ + 1).

Can this python code be done without using the isdigit() function. Please try to change the following code in the picture so it doesn't use isdigit().

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…

Given a positive integer n, the following rules will always create a sequence that ends with 1, called the hailstone sequence: If n is even, divide it by 2 If n is odd, multiply it by 3 and add 1 (i.e. 3n +1) Continue until n is 1 Write a program that reads an integer as input and prints the hailstone sequence starting with the integer entered. Format the output so that ten integers, each separated by a tab character (\t), are printed per line. The output format can be achieved as follows:System.out.print(n + "\t"); Ex: If the input is: 25 the output is: 25 76 38 19 58 29 88 44 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1 (NEED HELP IN JAVA PLEASE)

Ask the user how many integers that he/she wants to enter. Using a for loop, ask the user for that many integers. Then, display all those integers. use test case examples as a reference. Write code in Java

Use a while loop function instead of a for loop sing python
