Question 5: Write a program that inputs four strings that represent floating-point values, converts the strings to double values, sums the values and prints the total of the four values.

Your program will prompt the user for the following information: current population number of yearly births from the previous year number of yearly deaths from the previous year number of years into the future for your predictive value of the future population. You will then compute the following: birth rate death rate growth rate the predicted future population Assignment Notes: To allow the user to input the numeric data (such as current population) it is necessary to use the input function. The input function takes a string in parenthesis that prompts the user what to enter. The computer then waits until the user types a response, terminated by the user typing the Enter key. A string, as a sequence of characters, is returned to the variable on the lefthand side of the assignment statement.  For example:       currPopulation = input(“Enter the current US population”)   The data in currPopulation is a string (because that is what the input statement does) but we need it to be a number…

1. Write a program that does the following: - reads an unspecified number of integers - determines how many positive and negative values have been read - 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 the entire input is 0, the program displays "No numbers are entered except 0". Here is a sample run: Enter integers ending with e: 1 2 -1 3 e The number of positives is 3 The number of negatives is 1 The total is 5 The average is 1.25 2. A pentagonal number is defined as n(3n-1)/2 for n= 1, 2, ..., etc.. Therefore, the first few numbers are 1, 5, 12, 22, .... Write a method with the following header that returns a pentagonal number: public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line.…

Q5: Write a program that inputs three integers from the keyboard and prints the sum, average, product, smallest and largest of these numbers.

1 # Write a program that reads a single integer N from the user. 2 # It then prints the string: "Is N your favorite number?"

6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.

26.Temperature Conversion Write a program which prompts the user for a Fahrenheit temperature, convert it to Celsius temperature, and print out the converted temperature. Hint: Celsius temperature (Fahrenheit temperature – 32) ÷ 1.8 - Sample input and output: Fahrenheit temperature: 60 Celsius temperature: 15.56
